CUPS provides a portable printing layer for UNIX-based operating systems. It is developed and maintained by Easy Software Products to promote a standard printing solution and is the standard printing system in MacOS X and most Linux distributions.
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.
What's new in this version:
CUPS 1.2.10 fixes the init script used to start the scheduler, a recursion bug in the pdftops filter, and several other issues reported after the 1.2.9 release.
