The third public beta release of the Common UNIX Printing System
("CUPS") is now available for download from the CUPS web site
Binaries for several platforms are also available!
The Common UNIX Printing System provides a portable printing
layer for UNIX® operating systems. It has been developed by Easy
Software Products to promote a standard printing solution for
all UNIX vendors and users. CUPS provides the System V and
Berkeley command-line interfaces.
CUPS uses the Internet Printing Protocol (IETF-IPP) as the basis
for managing print jobs and queues. The Line Printer Daemon
(LPD, RFC1179), Server Message Block (SMB), and AppSocket
protocols are also supported with reduced functionality.
CUPS adds network printer browsing and PostScript Printer
Description ("PPD")-based printing options to support real world
applications under UNIX.
CUPS also includes a customized version of GNU GhostScript
(currently based off GNU GhostScript 4.03) and an image file RIP
that can be used to support non-PostScript printers.
Sample drivers are provided for HP DeskJet and LaserJet
printers. Drivers for over 1200 printers are available in our
ESP Print software.
