InterPress is a page description language developed at Xerox PARC, based on the Forth programming language and an earlier graphics language called JaM. As with many PARC projects, Interpress was not commercialized at its time of creation, and its primary effect on the world was to cause some of its creators (Chuck Geschke and John Warnock) to get fed up, form their own company, and publish their own version. The company in this case was Adobe Systems, and their version is known as PostScript. InterPress was used in some Xerox printers, and supported in Ventura Publisher, but it is not clear whether or not it achieved significant market-share. InterPress was also used as the output format for PARC's InterScript system, which was an editable word processor format for rich documents.
