Postscript is a page description language developed by Abode Systems, Inc. Unlike other types of printing languages, PostScript is a fully realized computing language. This enables it to be used on a variety of platforms. A PostScript file can be printed on any printer that contains a PostScript interpreter, even if the user no longer has access to the application in which the file was created. Originally used by Apple LaserWriters, PostScript is now supported by more than 5,000 software applications. Adobe's PostScript software is the basis for the Standard Page Description Language (SPDL) by the International Standards Organization (ISO).
PostScript graphic files are called Encapsulated PostScript files. The extension used for these files is ".eps." Many programs, such as PageMaker and Adobe Illustrator and Photoshop, allow the user to save documents in this format.
PostScript's ease of transport allows it to be an ideal printing mechanism for networks. Helper utilities for viewing postscript files on the Internet are Ghostscript and <"A HREF="http://www.cs.wisc.edu/~ghost/ghostview/index.html">Ghostview.
