CUPS is the standards-based, open source printing system for Mac OS X and other UNIX®-like operating systems.

CUPS (formerly an acronym for Common Unix Printing System) is a modular printing system for Unix-like computer operating systems which allows a computer to act as a print server. A computer running CUPS is a host that can accept print jobs from client computers, process them, and send them to the appropriate printer.
