NeXTSTEP adapted Display PostScript from Adobe Systems for use as its graphics engine.New from Adobe by Greg Scott, University of Michigan Computing News, vol.3, no.4, p.10-11. 1988-02-24. The integration of PostScript into the operating system allowed the NeXT Laser Printer and Color Printer to be significantly simpler and cheaper, while still maintaining speed and WYSIWYG accuracy in their printed output.NeXT Laser Printer by Kevin Ford, The Best of NeXT Collection.
