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.

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”

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

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

Brother Printer and Brother Ink Cartridge Problems and Troubleshooting
Even Brother Printers and Brother Ink cartridges are prone to offering a user a set of problems. After all, there are electronic machines and hence are liable to show problematic instances. The fact remains, however, that these problems could be solved easily and without you taking the printer to a service center. All you need to do is to use a few troubleshooting tricks.
Ink Runs Out Quickly
You have just changed your empty cartridge or have got it refilled. But once more, you find that your cartridge has run out of ink. The cause of this problem is not too hard to find. Brother printers are famous, in this case let’s just say ‘infamous’ for continuously cleaning the inkjets. Hence, they end up wasting a lot of ink. You need to keep this fact in mind. At the end of the day this is one of the positives of the Brother printers as the print head of the cartridges is less liable to get clogged or jammed.
Sudden Stoppage of Printer
Without any warning your printer chooses to stop working. The first thing that you must do in cases like these is to think about the kind of changes that you might have made to your system recently. These changes might not be compatible with your printing settings, giving rise to this problem. For example, if you had a Windows XP operating system installed on your system when you installed the printer and now have up-graded it to Vista, the driver of the printer might not be compatible with the latest version of the OS. This problem will be solved by downloading a different driver that will be fully compatible with the new Operating System that you have downloaded.
Smudging
If your printout has vertical smudges, then you have a problem. This problem is related to the Brother Ink cartridges. The first reason for this could be that they are low on ink. The other reason could be that the drum has worn down, through constant usage. Now, you need to decide whether you want to replace the drum of the printer, which is quite expensive, or you want to buy a whole new printer altogether.
The Error Message Problem
If you are a regular printer user, you might have been frustrated one time or the other by the number of printer error messages popping on the screen, one after the other! This is yet another problem with respect to Brother Printers. The best thing for you to do in this case would be to read the printer manual and basically understand what the error messages are tying to tell you. Also, read the error message carefully, and know what is wrong with the printing process. At times, all it requires for a solution is to restart the printers and its process. There are a varied number of errors that a printer is prone to, and most of these have been addressed in the printing manual.
