Binaries for several platforms are also available!
The Common UNIX Printing System provides a portable printing
layer for UNIX=AE 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 1500 printers are available in our
ESP Print Pro software.
CUPS is licensed under the GNU General Public License. Please

"binary distribution" rights.
Changes since the last release include:
- The IPP backend wasn't appending a 0-length chunk when
- You couldn't add a printer if there was a remote class
of the same name, and visa-versa.
- The setgid() and setuid() calls were backwards in the
- The scheduler didn't always log printer status
messages; this should be fixed now.
- Filter creation and death are now logged (debug level
only.) This should better aid filter debugging.
- The image library code was using lseek() after
rewind() to ensure that the file descriptor was at the
beginning of the file. This was needed for the TIFF
image handler but broke the rest of the file formats.=20
Moved the lseek() to the TIFF image handler...
