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 Xerox 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.
PARC was founded in 1970, and incorporated as a wholly owned subsidiary of Xerox in 2002. It is best known for inventing laser printing, Ethernet, the modern personal computer graphical user interface (GUI) paradigm, ubiquitous computing, and advancing very-large-scale-integration (VLSI).
Today PARC collaborates with sponsors and clients to discover novel business concepts and transfer scientific findings into production. Current research areas include biomedical technologies, "clean technology", user interface design, sensemaking, ubiquitous computing, large area electronics, and embedded and intelligent systems.
Most critics don't realize that computing research was a relatively small part of PARC; there were many researchers working in areas such as materials science at PARC, including pioneers in LCD and optical disc technologies.
