VPNs and Their Benefits

A VPN is an encrypted connection between private networks over a public network such as the Internet. The V stands for virtual, and the N stands for network. It is a technology that allows users on different switch ports to participate in their own network separate from, but still connected to, the other stations on the same or connected switch. The information from a private network is securely transported over a public network, the Internet, to form a virtual network. The P stands for private. To remain private, the trafﬁc is encrypted to keep the data conﬁdential. Virtual LANs are primarily a feature of network switches. Because most true hubs cannot perform segmentation based on MAC addresses, they cannot do VLANs. Although NICs are required in order to use a VLAN, VLANs are not a primary feature of them. Instead of using a dedicated Layer 2 connection such as a leased line, a VPN uses IPsec to form virtual connections that are routed through the Internet from the private network of the company to the remote site or employee host.
Beneﬁts of VPNs include the following:
■ Cost savings: VPNs enable organizations to use cost-effective third-party Internet
transport to connect remote ofﬁces and remote users to the main corporate site, thus
eliminating expensive dedicated WAN links and modem banks. Furthermore, with the
advent of cost-effective high-bandwidth technologies, such as DSL, organizations can
use VPNs to reduce their connectivity costs while simultaneously increasing remote
connection bandwidth.
■ Security:VPNs provide the highest level of security by using advanced encryption and
authentication protocols that protect data from unauthorized access.
■ Scalability: VPNs enable corporations to use the Internet infrastructure within ISPs
and devices, which makes it easy to add new users. Therefore, corporations are able to
add large amounts of capacity without adding signiﬁcant infrastructure.
■ Compatibility with broadband technology: VPNs allow mobile workers, telecommuters, and people who want to extend their work day to take advantage of high-speed, broadband connectivity, such as DSL and cable, to gain access to their corporate networks, providing workers signiﬁcant ﬂexibility and efﬁciency. Furthermore, high-speed broadband connections provide a cost-effective solution for connecting remote ofﬁces.

Print Quality Issues Printer Troubleshooting

Print Job Never Prints

If you send a print job and printer is not working, check the following things:

a) Is the printer turned on?
b)
c) All the cable are in working condition.

d) There is no problem is power source.

If every thing is well, the next step is to check the print sever print spooler status.

The print spooler is the hard disk space reserved for channeling print jobs from the PC to the printer. You can check the spooler status by two methods:

1. Click Start, Control Pannel, Printer and Faxes, and double click the printer icon.
2. Click the tiny printer icon in the system tray. This icon will be mostly there if print is failed to print.

The print spooler windows shows all the pending jobs. You can delete, start or pause jobs.

Print spoolers can overflow or become corrupt because of a lack of disk space or too many print jobs in the queue. The Printers window shows all the pending print jobs and enables you to delete, start, or pause jobs. The best answer is usually to delete the print jobs and try again. You might also run into a situation where the print jobs seem to spool, but then just vanish or “despool” as the jargon goes. The print spooler shows print jobs for a brief moment, but then nothing prints. Check the printer driver. An incorrect driver for the attached printer can cause this issue.

Incorrect Page Size

A print job that comes out sized incorrectly usually points to a user mistake in setting up the job. Check the Print dialog box for incorrect print parameters. Also check the Page Setup option in the relevant application. Make sure the user is setting up the page properly. If you know the page is set up correctly, recheck the printer drivers. If necessary, uninstall and reinstall the print drivers. If the problem persists, the printer’s print engine may be causing the trouble, but that is a possibility only when you continually get the same strangely sized printouts using a number of different applications.

Garbage Characters in Printout

Misaligned or garbage printouts invariably point to a corrupted or incorrect driver. Make sure you’re using the appropriate printer driver and then uninstall and reinstall the driver. If the problem persists, it’s possible that you’re asking the printer to do something it cannot do. For example, you might be printing to a PostScript printer with a PCL driver. Check the printer type to verify you haven’t installed the wrong type of driver for that printer. Try some of these diagnostic avenues:

• Make sure the printer cables are attached firmly and haven’t become loose.

• Turn off the power to the printer, and then turn it on again.

• To check the basic communication between the PC and the printer, try printing a plain text file—Notepad is excellent for that.

• Restart your computer. Many Windows and application problems can

be resolved simply by restarting your system.

• Reinstall your printer drivers. Drivers occasionally become corrupted and might need reinstalling.

• Check your resource settings for the parallel or USB port to verify no resource conflicts exist.

• Connect the printer to a different computer. If the printer continues producing garbage characters on the second computer, you know the problem lies within the printer.

• Try printing a smaller document. If you can print a smaller document, the problem may be insufficient memory in the printer. Insufficient memory can be remedied by adding more RAM to the printer.

Printer Not Responding

If the printer isn’t responding, check the easy things, first make sure the printer is turned on and the cables are securely and correctly attached. Make sure the printer is online. Make sure the application you’re printing from is sending the print job to the correct printer .Make sure you have the correct print driver installed for the printer. Try to print a test page. Try attaching the printer to a new computer. If nothing works, your printer might have to go to a printer repair facility.

Computer Network Security Tips

Security is very important for your computer networks. Security policies can cover hundreds of items. Here are some of the more common:
Notification What good is a security policy if no one knows about it? Give users a copy of the security policy when you give them their usernames and passwords. Computers should also display a shortened version of the policy when a user attempts to connect; for example, Unauthorized access is prohibited and will be prosecuted to the fullest extent of the law.” One hackerargued that since a computer did not tell him otherwise, anyone was free to connect to and usethe system.
Background Checks Do background checks on all network support staff. This may include calling their previous employers, verifying their college degrees, requiring a drug test, and
checking for any criminal background.
Equipment Access Disable all unused network ports so that nonemployees who happen to be n the building cannot connect a laptop to an unused port and gain access to the network. Also, place all network equipment under lock and key.
Wiring Network wires should not run along the floor where they can be easily accessed. Routers, switches, and concentrators should also not be hooked up in open office space. They should be in locked closets or rooms, with access to those rooms controlled by badge-swiping systems.
Door Locks/Swipe Mechanisms Be sure that only a few, key people know the combination to the cipher lock on data center doors or that only the appropriate people have badges that will allow access to the data center. Change lock combinations often, and never leave server room doors open or unlocked.
Accounts Each user should have their own, unique user account, and employees should not
share user accounts. Even temporary employees should have their own account. Otherwise, you
will not be able to isolate a security breach.
Badges Require everyone to wear an ID badge, including contractors and visitors, and assign
appropriate access levels to contractors, visitors, and employees.
Tracking Require badge access to all entrances to buildings and internal computer rooms.
Track and record all entry and exit to these rooms.
Passwords Reset passwords at least every month. Train everyone on how to create strong
passwords. Set BIOS passwords on every client and server computer to prevent BIOS changes.
Monitor Viewing Block computer monitors so that visitors or people looking through windows can’t see them. Be sure that unauthorized users/persons cannot see security guard stations and server monitors.
Cameras Cameras should cover all entrances to the building and the entire parking lot. Be sure
that cameras are in weather-proof and tamper-proof housings, and review the output at a security monitoring office. Record everything on extended-length tape recorders.
Mail Servers Provide each person with their own e-mail mailbox, and attach an individual
network account to each mailbox. If several people need to access a mailbox, do not give all of
them the password to a single network account. Assign privileges to each person’s network
account. You can then track activity to a single person, even with a generic address such as
info@mycompany.com.
DMZ Use a demilitarized zone for all publicly viewable servers, including web servers, FTP
servers, and e-mail relay servers. Do not put them outside the firewall. Servers outside the fire-
wall defeat the purpose of the firewall.
Mail Relay Use a mail-relay server for e-mail. E-mail traffic should not go straight to your
production servers. That would enable a hacker to directly access your server as well. Use a relay server in a DMZ.
Patches Make sure that the latest security updates are installed after being properly tested on
a nonproduction computer.
Backups Store backup tape cartridges securely, not on a shelf or table within reach of someone
working at the server. Lock tapes in a waterproof, fireproof safe, and keep at least some of your
backups off site.
Modems Do not allow desktop modems for any reason. They allow users to get to the Internet
without your knowledge. Restrict modem access to approved server-based modem pools.

Paper Standard Sizes and Conversion

Paper sizes are categorized into two standards, the ISO standard and the North American size standard. ISO standard has A, B and C series, while NA standard is based on inches.

ISO Size Standards

"A-series", for general printing

"B-series", for posters

"C-series", for envelopes, postcards, and folders

The "A" series is used most commonly with sizes ranging from A0,which is the largest, down to A8. The A-series sizes are represented as a part of the area of one square meter with a length to width ratio of 1.414. Size A0 is equivalent to the area of one square meter while each smaller size being 50% of the size of the preceding one. A1 is 50% of the area of A0; A2 is 50% of A1, and so on. Another way to look at it is that when an A0 sheet cut in half yields two A1 sheets, and an A1 sheet cut in half yields two A2 sheets.

North American Size Standards

Although the ISO size standards are common in many parts of the world where the metric system is the established standard for measurement, North American sheet sizes are based on inches. The most common size of cut sheet for copier/printers is 8.5”x11” (Letter Size) that is based on basis size of 17”x22”. (Letter being the quarter of the size of the 17” x 22”). Other popular sizes are 8.5”x14” (Legal Size), and 11”x17” (Ledger Size). The other sizes such as 12”x18” and 9”x12” are becoming popular for color applications. These paper sizes are based on paper sizes used in offset printing.

Engineering paper sizes are also in this category with sizes such as 9”x12” (A size), 12”x18” (B size), 18”x 24” (C size), 24”x36” (D), 36”x48” (E size).

NAS To ISO Conversion:

To convert the sizes and weights from North American Standards to ISO standards we have to use a little math. Let’s take a look at how to convert size and weight from North American standards to ISO and ISO to North American standards. As defined by ISO, paper size is described in metric measure, more specifically millimeters. The first conversion ratio that we need to know is how many millimeters there are in an inch. There are 25.4 millimeters in one inch. The conversion procedure involves multiplying the inches by the conversion factor (25.4), and rounding off to the nearest millimeter.

For example:

To convert the size of the standard 8 1/2 x 11 letter size from inches to millimeters:

Multiply the width in inches by the conversion factor:

8 1/2” x 25.4 mm = 215.9 mm

Round the product off to the nearest millimeter:

216mm

Multiply the length in inches by the conversion factor:

11” x 25.4 mm = 279.4 mm.

Round the product off to the nearest millimeter:

279mm

The measurement therefore becomes:

US Letter (8 1/2” x 11”) = 216 mm x 279 mm.

This process can be reversed to determine the inch size of paper (or anything else) initially describe in millimeters.

We saw earlier that ISO A4 paper is 210mm x 297mm. How would we find out what the inch size of A4 is?

We would take the width and divide by the conversion factor:

210/25.4 = 8.2677

Round the quotient off to the nearest 1/4 inch:

8 1/4

Divide the length by the conversion factor:

297/25.4 = 11.6929

Round the quotient off to the nearest 1/4 inch:

11 3/4

The measurement therefore becomes:

ISO A4 (210mmx297mm) = 8 1/4” x 11 3/4”

SSL Communication Flow

The different negotiations used by SSL, including cryptographic algorithms, key exchanges, and certificates, are performed concurrently.
Step 1: The client sends a hello record that includes the version of SSL being used (usually TLS 1.0), a list of viable cipher specifications, and a random challenge.
Step 2: The server responds with the selected cipher set and either a server certificate
(server-side certificate) or part of a key exchange. The server may also request a certificate from the client (client-side certificate). The server generates a response to the random challenge that can be validated by the client. This allows the client to identify the server—preventing potential MitM attacks between the client and the server. This does not validate the server; it only prevents a MitM from hijacking the established connection.
Step 3: If the server provides a certificate, then the client contacts a certificate authority (CA) and validates the certificate. Although it is considered secure for the client to validate the certificate, there is nothing in SSL requiring certificate validation. Contacting a CA can add time to the initial connection. If speed is an issue, then the client may choose to not validate the server’s certificate. In addition, some cipher sets, such as SSL3-NULL-MD5 and SSL3-RC4-MD5, do not require a server certificate.
Step 4: The client responds to the server, initiating a key exchange. If a clientside certificate is available, then the client may provide it. (If the server requests a client-side certificate, then one must be provided.) If the server provides a certificate, then the client also provides a message encrypted with the certificate. Similar to Step 2, this allows the server to identify but not validate the client.
Step 5: If the client provides a certificate to the server, then the server may contact a CA to authenticate the client. As with Step 3, the server is not required to validate the client, but servers usually validate client-side certificates.
Step 6: The server sends an encrypted handshake to complete the validation process. At this point, the negotiations and exchanges are complete; the clientand server are both authenticated and validated. An attacker cannot act as a MitM or impersonate the client and server. All further communication uses the agreed upon symmetrical encryption algorithm, which is seeded with the negotiated key exchange values.

Simple TLS handshake

A simple connection example , illustrating a full handshake, follows:

A client sends a ClientHello message specifying the highest TLS protocol version it supports, a random number, a list of suggested cipher suites and compression methods.
The server responds with a ServerHello message, containing the chosen protocol version, a random number, cipher suite, and compression method from the choices offered by the client. The server may also send a session id as part of the message to perform a resumed handshake.
The server sends its Certificate message (depending on the selected cipher suite, this may be omitted by the server).
The server sends a ServerHelloDone message, indicating it is done with handshake negotiation.
The client responds with a ClientKeyExchange message, which may contain a PreMasterSecret, public key, or nothing. (Again, this depends on the selected cipher.)
The client and server then use the random numbers and PreMasterSecret to compute a common secret, called the "master secret". All other key data for this connection is derived from this master secret (and the client- and server-generated random values), which is passed through a carefully designed "pseudorandom function".
The client now sends a ChangeCipherSpec record, essentially telling the server, "Everything I tell you from now on will be encrypted." The ChangeCipherSpec is itself a record-level protocol, and has type 20, and not 22.
Finally, the client sends an encrypted Finished message, containing a hash and MAC over the previous handshake messages.
The server will attempt to decrypt the clients Finished message, and verify the hash and MAC. If the decryption or verification fails, the handshake is considered to have failed and the connection should be torn down.
Finally, the server sends a ChangeCipherSpec and its encrypted Finished message, and the client performs the same decryption and verification.
At this point, the "handshake" is complete and the application protocol is enabled, with content type of 23. Application messages exchanged between client and server will be encrypted.

Control Codes

Control Codes
A control code is a character that initiates a printer function, for example
Carriage Return (CR), Line Feed (LF), Form Feed (FF), etc.
Carriage Return (CR)
A carriage return is a special code that moves the cursor (or print head) to the beginning of the current line. In the ASCII character set, a carriage return has a decimal value of 13 (0D Hex).
Line Feed (LF)
A line feed is a code that moves the cursor on a display screen down one line. In the ASCII character set, a line feed has a decimal value of 10 (0A Hex).
On printers, a line feed advances the paper one line.
Form Feed (FF)
Printers that use continuous paper normally have a form feed button or command that advances the paper to the beginning of the next page.
A special character that causes the printer to advance one page length or to the top of the next page. In systems that use the ASCII character set, a form feed has a decimal value of 12 (0C Hex).

HP Printer Error Codes

Here is a list of common error codes along with troubleshooting tips for HP LaserJet printers.

Error code 02: Warm up issues

Error code 02 indicates that the I/O cable is bad or hooked up incorrectly and/or there is communication problem between computer and printer. Other causes are bad D.C controller, badFuser Assy or bad D.C power supply.

Error code 11: Out of paper

This means that your HP LaserJet is most likely short of paper. Check to see if the sensor arm of the paper tray is damaged or caught somewhere. Check if the tray is empty of paper. It could also be that the paper cassette is missing or the PS2 flag is damaged.

Error code 14: Absence of toner cart

Error code 14 indicates that the toner cartridge is either not properly seated or installed. It could also mean the sensitivity tabs are missing or that the toner cartridge itself is of bad quality. Make sure to check on the right hand tabs of the toner cartridge and that the switch actuator is not bent.

ERROR CODE 16: TONER LOW

Error code 16 indicates that the toner is low or uneven in the cartridge. Shake the toner well. Check the toner cartridge contact point, if necessary clean them with a blower brush. Defective main control board or high voltage power supply may also be the cause of this code.

Error code 22: Configuration error

These error codes are typically associated with improper configuration for the computer or the printer. Make sure the I/O cable isnt damaged. Check if the I/O port on the printer is damaged or not. Also check the EIO card inside slot X of your HP LaserJet printer. Check to see if it has overflowed.

ERROR CODE 24: JOB MEMORY FULL

This code shows that printer job memory is full. This may happen while printing a complex print job. If you have regular complex printing jobs than it is better to increase the memory. Check the specification of you printer to confirm that it support additional memory.

Error code 30: PS error

PS errors refer to a postscript firmware problem. For this you will need to get a new firmware chip for your HP LaserJet to function normally again.

Error code 40: Transfer error

This usually means that there is a disconnection between data transferring from your PC to your HP LaserJet printer. However, it can be rectified if you check on the MIO card. It should have no defects.

ERROR CODE 49. A COMMUNICATION OR CRITICAL FIRMWARE ERROR

This is a communication error code with the application that is being used. Go back to a different software program and see if a job will print. If message persists turn printer off then on. If message still there when the network cable is disconnected. Up grade firmware in jetdirect card and the formatter board.

Error code 52: Improper scanner speed

This error code implies that the HP LaserJet scanner is having faulty speeds. Check if the scanner motor is damaged and also check if the cable assembly is faulty or not. Sometimes this could be temporary as the scanner maybe facing startup issues.

ERROR CODE 68 - ERROR IN NVRAM, SERVICE ERROR NVRAM FULL

Possible Causes: This is temporary error code. If turning the power on and Off does solve it the formatter board may be defective.

ERROR CODE 69 - DUPLEXER ERROR HAS OCCURRED

Temporary duplexer error. Reseat duplexer and perform a service test. If problem persists perform a paper path test.

Error codes 70 and 71: damaged MIO card

This indicates that the MIO card also called SIMMS is faulty or damaged. Either the SIMM slot or the SIMM itself is not compatible with your HP LaserJet printer. That means you will need to get a new SIMM which is compatible.

ERROR CODE 80 - DEFECTIVE NETWORK CARD, OR FORMATTER BOARD.

Possible Causes: Improper MIO connection, replace the network cable.
Defective MIO / Network card
Replace the formatter board.

HP Laserjet Error Codes 13 1 PAPER JAM OPEN INPUT TRAYS

This Paper-delay jam at paperfeed area.
how to solve

1. Ensure that paper trays are loaded and adjusted properly so media can feed from the tray. It might be necessary to reduce the stack height of media in the tray. 2. Check the input area for obstructions such as media in the path. Also check to see if the registration assembly damaged or unseated. 3. Replace any defective sensors or flags. 4. Verify the media meets the specifications. 5. Check the pickup feed and separation rollers for unusual wear. Replace as needed. 6. Rotate the media in the input tray by 180° and/or turn it over

Network security

A major concern of network management is data security. Maintaining LAN data security means:

# maintaining data integrity

# securing the LAN from unauthorized access

# securing the LAN from computer viruses

# ensuring the availability of network components and access.

Because security is a primary concern and responsibility of network managers, you will not normally be given direct access to network settings and configurations when working on network printer installations.

Data integrity
The protection of a network’s data resource is achieved in a number of ways:
# by the use of uninterruptible power supplies (UPS) to allow the network and servers long enough to keep running through minor power outages and to shut down gracefully during long outage
# by providing redundant hardware, including redundant hard drives, so that secondary systems can take over in the event of the failure of the primary system
# by regular backups of data, so that in the event of a loss of integrity data can be restored with a minimum of lost work.
Protection from unauthorized access
Most networks have a system allowing access to only authorised users. Security systems can
allocate rights such as access to resources like applications, printers, directories and specific files. Normal security requires that users have a unique ID and password to access network resources. If an organisation wishes to grant an external user access to the network, a user ID and password will have to be issued, for a limited period of time.

To reset the HP C6657A 57 or HP C8728A 28

To reset the HP C6657A (#57) or HP C8728A (#28):
1. Refill your cartridge using your Mr. Ink Jet refill kit.

2. Following the diagram at right, place a piece of adhesive tape covering the only the blue colored contact (a contact is the individual copper square). Make sure that only that contact is covered and no others. *Please note that the contacts shown are colored for illustrative purposes only. You will not have blue or red contacts on your cartridge.

3. Place cartridge in the printer. The printer may tell you that there is a problem with your cartridge. Ignore this message. The printer may print an alignment page. If so, allow it to do so.

4. Take the cartridge out of the printer. Leave the tape from blue contact. Place another piece of tape over the red colored contact. Make sure that only that contact is covered and no others. *Please note that the contacts shown are colored for illustrative purposes only. You will not have blue or red contacts on your cartridge.

5. Follow step 3 again.

6. Take the cartridge out of the printer for the final time. Take the remaining tape off and place back in the printer. The printer should print out an alignment page and the estimated ink level in the toolbox should read full.

Reset Method 2:

If Reset Method 1 did not work on your printer, you can cycle cartridges through to reset the level. You will need two extra cartridges and the one you refilled. First, put the refilled cartridge in the printer. Allow it to recognize the cartridge and print an alignment page. Take that cartridge out and place in the first extra cartridge. Allow it to recognize and print an alignment page. Take the first extra cartridge out and place the second extra cartridge in. Allow it to recognize and print an alignment page. Take the second extra cartridge out. Place the refilled cartridge back in the printer. It will print an alignment page and then the estimated ink level will be reset to full.

What are networks

A network is a number of computers and peripherals linked together so that data can be passed between them. The rise in the popularity of networks has led to a variety of approaches to network construction. To help distinguish between different approaches, engineers categorise
networks according to:
size
the way they are arranged (the topology)
the set of rules they observe when com
municating (the protocols)
the model or architecture of how the
network functions (peer-to-peer or
client/server).
Network Transmission

The commonest forms of data transmission in a network use packets, or frames, of data. A
packet is simply a block of data that originates at one point in the network and is destined for another point. The packets of data are transmitted via the cabling or wireless communication used by the network.
In order to identify the destination of the data packet, an address is attached to it. The address is a unique identifier of the destination point, whether it is a workstation, printer, or other network component. The address attached to the packet ensures that it is directed to the right part of the network, and that only the addressee will receive it. The structure and addressing of packets is determined by the protocols of the network operating system. Overall standards are set by the IEEE (Institute of Electrical and Electronics Engineers). Standard 802.2 defines framing and addressing standards.
LANs and WANs

Generallay networks are divided into to catagories:
1. LANs (Local Area Networks) and
2. WANs (Wide Area Networks).

Postscript and its Benefits

Adobe PostScript is the worldwide printing and imaging standard. It is widely used by print service providers, publishers, corporations, and government agencies around the globe, giving you the power to print visually rich documents reliably. Adobe Postscript printing technology is licensed to original equipment manufacturers (OEMs) for building high-performance printing systems and print workflow solutions. As a scalable architecture, it can be easily integrated into a wide range of devices and technologies while maintaining the high quality and performance.
It has become the printing and imaging technology of choice for corporations, publishers and government agencies throughout the world. 75 % of all commercial publications are printed on Adobe PostScript devices. These include
• black/white printers,
• colour printers,
• image setters,
• latesetters and
• direct digital printing systems.
By the way, Postscript is not limited to be used in printers or other devices used in the professional printing process. Also computer screens have been driven by Postscript.
The Postscripts language has had two major upgrades. The first version, known as PostScript Level 1, was introduced in 1984. Post script 1 was implemented by the Apple on the Apple LaserWriter printer. Postscript supported many new features at that time like outline fonts and vector graphics so it became popular among graphic printers. The structure of the Postscripts language, which is similar to a conventional computer programming language, meant that these advanced features could be used in a very versatile and creative manner to create complex images and designs. Apple continued to upgrade this language and introduced the Apple LaserWriter Plus. The new printer had more memory and many more outline fonts.
Nowadays, Postscript has become an industry standard for the typesetting of books, magazines and other complex publications.
PostScript Level 2
PostScript Level 2 was introduced in 1991, and included several improvements: improved speed and reliability, support for in-RIP separations, image decompression (for example, JPEG images could be rendered by a Postscripts program), support for composite fonts, and the form mechanism for caching reusable content.
The disadvantage of Postscripts was its speed. Postscript Level 1 required an enormous amount of processing power, and was often very slow. The capabilities of the various releases were also confusing, as the language was enhanced as each new printer was equipped with PostScript, extensions to PostScript were created to cope with colour, patterns, printers with multiple paper trays, duplex etc. PostScript Level 2 incorporates all the enhancements made to the original PostScript, setting a new baseline for the language. PostScript Level 2 is entirely backwards compatible with the original PostScript, and will produce the same image for a job as a PostScript Level 1 printer.
PostScript Level 3
Postscript level 3 was introduced in 1997, supports more fonts, better graphics handling, and includes several features to speed up PostScript printing.
PostScript 3 (Adobe dropped the "level" terminology in favor of simple versioning) came at the end of 1997, and along with many new dictionary-based versions of older operators, introduced better color handling, and new filters (which allow in-program compression/decompression, program chunking, and advanced error-handling).
The new graphics capabilities include
• smooth shading,
• idiom recognition,
• masked images,
• finer colour controls,
• superscreens, and
• fast image.
Other improvements of PostScript Level 3 include
• In–RIP Trapping,
• direct PDF printing, and
• DeviceN.
In–RIP Trapping is a new capability of the PostScript 3 interpreter that executes trapping commands at the raster image processor (RIP), automating complex and time consuming prepress tasks. Trapping is specified, then rendered at print time rather than as a separate production step prior to RIPping. Direct PDF printing is an optional capability of the Adobe PostScript 3 interpreter that improves workflow productivity by allowing the RIP to accept and print files in the Portable Document format (PDF) without
printing through an application – the PDF files don’t have to be opened with an application and then be printed from that application but can be sent directly to the RIP.
DeviceN is a new Level 3 operator that handles any number of colours, from duotones and tritones, to Haxachrome™ and beyond, in a composite workflow. This feature is supported by Adobe Photoshop 5.0. It makes prepress applications easier to use and
more efficient, representing all colour on one single page, instead of using one page per colour.

Benefits of Adobe Postscript are :

Quality. Adobe Postscript was designed from the outset to work seamlessly with every major operating system and color management system and prints anything, from everyday business correspondence to complex colorful brochures. The printed version always looks exactly as it does on-screen without reformatted pages or misplaced artwork.
Network. With support on every major computer platform Adobe Postscript devices are ideal for networks large and small.
PostScript became commercially successful due to the introduction of the graphical user interface, allowing designers to directly lay out pages for eventual output on laser printers. However, the GUIs own graphics systems were generally much less sophisticated than PostScript; Apples QuickDraw, for instance, supported only basic lines and arcs, not the complex B-splines and advanced region filling options of PostScript. In order to take full advantage of PostScript printing, applications on the computers had to re-implement those features using the host platforms own graphics system. This led to numerous issues where the on-screen layout would not exactly match the printed output, due to differences in the implementation of these features.
Print documents regardless of printing device computer platform or operating system. This is device independence. Adobe Postscript language file is independent of the device that created it and the device that prints it.
Print documents not created by the user including documents sent by email imported from new media such as CD-ROM or downloaded from the Internet.
Select the best device for users needs from a wide variety of Adobe Postscript devices currently available.
Print easily across networks large or small which incorporate a variety of computers operating systems, applications and printing systems anywhere in the world.
Adobe Postscript printers and systems work independently of any network configurations ensuring seamless operation in any environment.
Print in color with the assurance that regardless of device the colors in the output will be what the user intended.
Performance. Adobe continuously optimizes the Adobe Postscript system to enhance performance. The flexibility of Adobe Postscript offers manufacturers the freedom to optimize the printing environment with technologies such as memory reduction compression and coprocessors.
Compatibility. Whether using Microsoft Windows Apple Macintosh, UNIX, OS/2, DOS, or a networked combination, Adobe Postscript delivers consistent high-quality results.
Typically, PostScript programs are not produced by humans, but by other programs.

PostScript Level 3 offers the following improvements over Level 2.
1. Faster printing and improved quality
2. New features to support the increasingly complex documents available via the Internet, such as three-dimensional images.
3. For complex documents, PostScript Level 3 processes each component as a separate object to optimize imaging throughput.
4. The resident font set will be expanded to provide compatibility with the resident fonts of all leading operating systems, enhancing performance by reducing font downloading.
5. PDF has been integrated into Adobe PostScript Level 3.
6. Ease of use, ease of connection and ease of printer management all in one environment, including Web based printer management, support for all industry standard remote management technologies, and a single step CD-ROM installer for all drivers, fonts and value-added software.
7. PlanetReady Printing: Allows printing technology to meet local language needs world-wide.
PostScript Fonts
PostScript is an object-oriented language, meaning that it treats images, including fonts, as collections of geometrical objects rather than as bit maps. PostScript fonts are called outline fonts because the outline of each character is defined. They are also called scalable fonts because their size can be changed with PostScript commands. Given a single typeface definition, a PostScript printer can produce a multitude of fonts. In contrast, many non-PostScript printers represent fonts with bit maps. To print a bit-mapped typeface with different sizes, these printers require a complete set of bit maps for each size.
The principal advantage of object-oriented (vector) graphics over bit-mapped graphics is that object-oriented images take advantage of high-resolution output devices whereas bit-mapped images do not. A PostScript drawing looks much better when printed on a 600-dpi printer than on a 300-dpi printer. A bit-mapped image looks the same on both printers.
Every PostScript printer contains a built-in interpreter that executes PostScript instructions. If your laser printer does not come with PostScript support, you may be able to purchase a DIMM that contains PostScript.

Encapsulated PostScript is File format of Adobes PostScript page description language used in high quality computer printers. EPS is device independent, images can be transferred between different applications as well as sized and printed on different (EPS-compatible or emulating) printers, without any loss of image quality. It exploits the full capabilities of the device it is used on. A typical usage of EPS is to save an illustration created in a drawing program as an EPS file and to import it into a page layout program such as InDesign or QuarkXPress. The layout artist would place and resize the image, which would either be the embedded preview or rendered directly from the PostScript code. The EPS images would be saved in the page layout program.
It can contain any combination of text, graphics, and images. An EPS file is the same as any other PostScript language page description, with some restrictions.
An EPS file must be a conforming file, that is, it must conform to the Adobe Document Structuring Conventions (DSC). At a minimum, it must include a header comment,%!PS-Adobe-3.0 EPSF-3.0, and a bounding box comment,%%BoundingBox: llx lly urx ury, that describes the bounds of the illustration. (The specification does not require the EPSF version, but many programs will reject a file that does not have it.)
The EPS file should make no environment-sensitive decisions (the importing application may be trying to attain some special effect, and the EPS program shouldnt mess this up), although it can use some device-dependent tricks to improve appearance such as a snap-to-pixel algorithm.
The EPS file must not use operators that initialize or permanently change the state of the machine in a manner that cannot be undone by the enclosing applications use of save and restore (eg. the operators starting with "init" like initgraphics). As a special case, the EPS program may use the showpage operator. The importing application is responsible for disabling the normal effects of showpage.
The EPS file can contain any combination of text, graphics, and images. An EPS file is the same as any other PostScript language page description, with some restrictions.

EPS files also frequently include a preview picture of the content, for on-screen display. The idea is to allow a simple preview of the final output in any application that can draw a bitmap. Without this preview the applications would have to directly render the PostScript (PS) data inside the EPS, which was beyond the capabilities of most machines until recently. Another advantage of the image preview is that if the graphic contained by the EPS is not to be modified itself but e. g. only to be placed inside a page layout using a layout software, the computer has less work to display only the small size preview instead of the high resolution image.
There are three preview formats providing the preview option for different platforms:
• PICT (Apple Macintosh),
• TIFF (IBM compatible, especially Microsoft Windows),
• EPSI (platform independent).
PICT
PICT is a graphics file format introduced on the original Apple Macintosh computer as its standard metafile format. It allows the interchange of graphics (both bitmapped and vector), and some limited text support, between Mac applications, and was the native graphics format of QuickDraw. With the change to Mac OS X, PICT was dropped in favour of Portable Document Format (PDF) as the native metafile format, though PICT support is retained by many applications as it is so widely supported on the Mac.
TIFF
A widely used bitmapped graphics file format developed by Aldus and Microsoft that handles monochrome, gray scale, 8-and 24-bit color. TIFF allows for customization, and several versions have been created, which does not guarantee compatibility between all programs.TIFF files are compressed using several compression methods. LZW provides ratios of about 1.5:1 to 2:1. Ratios of 10:1 to 20:1 are possible for documents with lots of white space using ITU Group III and IV compression methods (fax).
Portable Document Format (PDF)
Portable document format, a universal computer file format that preserves all the fonts, formatting, colors, and graphics of any source document, regardless of the application and platform used to create it; the open de facto standard for electronic document distribution worldwide.
A PDF file delivers the single “digital master” for use in electronic, printed, and mixed workflow environments, ensuring a consistency across all media types. The Adobe PDF file format is ideally suited for technical publications, as it can include photographic images, diagrams, graphs etc. The PDF document can be widely distributed across many computer platforms. To read the PDF format, you require a copy of the Adobe acrobat reader, which can be obtained free of charge from the Internet or from many magazine publications on distributed CD–ROM.
The PDF combines three technologies:
1. A sub-set of the PostScript page description programming language, for generating the layout and graphics.
2. A font-embedding/replacement system to allow fonts to travel with the documents.
3. A structured storage system to bundle these elements and any associated content into a single file, with data compression where appropriate.
PostScript Printer Descriptions (PPDs)
PostScript Printer Description (PPD) files are created by vendors to describe the entire set of features and capabilities available for their PostScript printers. It is a small file that contains information about the characteristics of a certain PostScript printer. These informations are used by the PostScript printer driver to provide full access to the printer’s features
