What is PostScript?

Monday, December 3, 2007
Adobe® PostScript® 3™ is the worldwide printing and imaging standard. The PostScript programming language was originally developed by Adobe Systems to communicate complex graphic printing instructions to digital printers. It is now built into many laser printers for high-quality rendering of both raster and vector graphics.

An important feature of the PostScript language is that it is device independent. This means that it produces good-looking images regardless of the resolution or color rendering method of the output device, and it takes full advantage of the capabilities built into the device. The Adobe Portable Document Format (PDF) is a more structured, compact subset of the PostScript language. Almost anything that can be done in PostScript can be done in PDF.

Type 1 fonts are a specialized form of PostScript program and are the original file format used for type display on all PostScript printers. The PostScript language was later extended to provide support for the later TrueType and OpenType® font standards. Any new Adobe PostScript language device made today supports all three font standards.
