CUPS is the standards-based, open source printing system developed by Apple Inc. for Mac OS® X and other UNIX®-like operating systems.
CUPS uses the Internet Printing Protocol ("IPP") as the basis for managing print jobs and queues and adds network printer browsing and PostScript Printer Description ("PPD") based printing options to support real-world printing.
CUPS: Common UNIX Printing System is the definitive guide to CUPS.
THIS PROJECT IS NOW PART OF CUPS
The CUPS Driver Development Kit (DDK) provided a suite of standard drivers, a PPD file compiler, and other utilities that can be used to develop printer drivers for CUPS and other printing environments. This software is now part of the standard CUPS release as of CUPS 1.4.0.
The CUPS driver for Windows is an extension for the Windows 2000 PostScript driver that is supported by CUPS 1.2 and higher. The driver adds support for the job-billing and page-label options.
THIS PROJECT IS DISCONTINUED AND ALL ADDITIONS HAVE BEEN MERGED INTO GPL GHOSTSCRIPT.
ESP Ghostscript was a customized version of Ghostscript based off GPL Ghostscript 8.15. All changes from ESP Ghostscript were merged into GPL Ghostscript 8.60.
The CUPS printer driver repository is an on-line resource for finding PPD files to use with CUPS.
The tifftops filter converts multipage TIFF files to a (DSC conforming) PostScript stream. The filter is written in Perl (5.83 ot higher). The TIFF handling and conversion routines are completely written in PostScript, thus Ghostscript (version 7.0 or higher) is needed.
