PostScript is a page description language developed by Adobe, most commonly used as a printer language. It is a turing complete stack based interpreted programming language. There are several variants of PostScript including Encapsulated PostScript (eps), and Display PostScript. PostScript can be seen as a 2D graphics programing language, and indeed, a variant called Display PostScript has been used in the past for actual computer graphics, specifically as the drawing API for NeXTSTEP. PostScript is still in use, Apple uses a variant of PostScript in their new Quartz drawing system for MacOSX, and various printers still use it.
