Interpress

Interpress is a page description language developed at Xerox PARC, based on the Forth programming language^[1] and an earlier graphics language called JaM. PARC failed to commercialize it, so its creators, Chuck Geschke and John Warnock, founded Adobe Systems in 1982, and developed PostScript.^[2] Interpress is used in some Xerox printers, notably the DocuTech Network Production Publisher, and is supported in Xerox Ventura Publisher. It also serves as the output format for PARC's InterScript, a rich text word processor. Interpress describes the desired or ideal appearance of a document that has been completely composed by some other process (emitter). All line ending, hyphenation, and line justification decisions, and in fact all decisions about the shapes and positions of the images, are made before creating the master. As a device-independent format, it allows printing on various devices while preserving the intended layout.
