This is a place for all things related to printing.
CUPS is a printing system intended as a replacement for the Berkeley and System V printing systems. It was created by Easy Software Products (ESP) but today is owned, developed and maintained by Apple Inc, with the original owner of ESP, Michael R. Sweet, being Senior Printing System Engineer. In the days of ESP ownership CUPS was officially known as the Common UNIX Printing System.
The CUPS printing system used in Debian involves complex interactions between the programs contained in many packages. The scheduler, cupsd, is at the heart of the system, but support from a filtering system, and a large array of packages is necessary for successful, effortless printing on a wide variety of printers. Having said that, the system appears to work well and there is little sign that Debian users have any great difficulty in setting up local or networked printers and getting them to function correctly. This page is intended to help maintain that situation.
CUPS is the default printing system for Debian but the Berkeley LPR software is also in the archives as lprng. It cannot co-exist with cups on the same system.
