PostScript and Interpress: A Comparison (1985)
Musings — mostly about color art, science, and technology
Bob Sproull and William Newman, of Xerox PARC, developed a relatively device-independent page image description scheme, called "Press format", which was used to instruct raster printers what to print. As part of an extensive grant program to selected universities, Xerox donated Dover printers and made documentation of the Press format available under a nondisclosure agreement. I am sure somewhere the messages are archived, but Peter Crean's recent account of XGP and the beginnings of digital printing prompts me to preserve from bit-rot an important historical post by Brian Reid on LaserLovers↑.pa@xerox.com.
