PostScript is a page description language that sends printing instructions to a PostScript device. All the elements in a print job (for example, curves and text) are represented by lines of PostScript code that the printing device uses to produce the document.
PostScript is not the only method for sending printing instructions, and some printing devices are not compatible with PostScript. However, there are several functions that are unavailable when you do not use PostScript. For example, you cannot adjust halftone screens.
There are three levels of PostScript. PostScript 1, the first PostScript language, has certain limitations (these are described below). PostScript 2 greatly reduces potential printing errors. PostScript 3, the latest version of PostScript, is faster than previous versions which have been largely eliminated in PostScript 2 or PostScript 3.
