However, the cost of implementation was high computers output raw PS code that would be interpreted by the printer into a raster image at the printer's natural resolution. For a time an interpreter (sometimes referred to as a RIP for Raster Image Processor) for the PostScript language was a common component of laser printers, into the 1990s. The combination of technical merits and widespread availability made PostScript a language of choice for graphical output for printing applications. In March 1985, the Apple LaserWriter was the first printer to ship with PostScript, sparking the desktop publishing (DTP) revolution in the mid-1980s.

At about this time they were visited by Steve Jobs, who urged them to adapt PostScript to be used as the language for driving laser printers. They, together with Doug Brotz, Ed Taft and Bill Paxton created a simpler language, similar to Interpress, called PostScript, which went on the market in 1984. Warnock left with Chuck Geschke and founded Adobe Systems in December 1982. This work later evolved and expanded into the Interpress language. In 1978 John Gaffney and Martin Newell then at Xerox PARC wrote J & M or JaM (for 'John and Martin') which was used for VLSI design and the investigation of type and graphics printing. But Press, a data format rather than a language, lacked flexibility, and PARC mounted the Interpress effort to create a successor. In 1975-76 Bob Sproull and William Newman developed the Press format, which was eventually used in the Xerox Star system to drive laser printers. At that time Gaffney and John Warnock were developing an interpreter for a large three-dimensional graphics database of New York Harbor.Ĭoncurrently, researchers at Xerox PARC had developed the first laser printer and had recognized the need for a standard means of defining page images. The concepts of the PostScript language were seeded in 1976 by John Gaffney at Evans & Sutherland, a computer graphics company. It was created at Adobe Systems by John Warnock, Charles Geschke, Doug Brotz, Ed Taft and Bill Paxton from 1982 to 1984. It is a dynamically typed, concatenative programming language. PostScript ( PS) is a page description language in the electronic publishing and desktop publishing realm.
