Display PostScript

Display PostScript, or DPS, is a version of the PostScript page decription language adapted by Adobe Systems so that a computer screen accurately displays what is intended to be printed in WYSIWYG fashion.

History
Steve Jobs of NeXT was an early adopter of Display PostScript technology. However, Mac OS X (the successor to NeXTSTEP) replaced Display PostScript with a new PDF-based imaging model called Quartz to avoid paying licensing fees to Adobe.
