What is PostScript?
| PostScript from Adobe |
|
A page description language (PDL) from Adobe that is used extensively on all computer platforms. It is the de facto standard in commercial typesetting and printing houses. Most all accept and may even require PostScript files as electronic input. PostScript commands do not drive the printer directly. They are language statements in ASCII text that are translated into the printer's machine language by a PostScript interpreter built into the printer. Fonts are scaled to size by the interpreter, thus eliminating the need to store a variety of font sizes on disk. PostScript Level 2, downward compatible with original PostScript, adds data compression and enhancements, especially for color printing. Level 3 adds more enhancements and native fonts and the ability to directly support more formats, including HTML, PDF, GIF and JPEG. Encapsulated PostScript (EPS) is a subset of PostScript used to exchange a single graphic image in the PostScript format. |
