Hollywood, MD (September 13, 2004) -- Easy Software Products today announced the 1.1.21 release of the Common UNIX Printing System ("CUPS"), an IPP/1.1-based printing system for UNIX®

CUPS 1.1.21 is primarily a bug fix and performance tuning release and includes fixes for the IPP, LPD, parallel, serial, and USB backends, authentication and status processing issues in the CUPS API, and various PostScript and PDF printing issues. The new release also adds support for Zebra label printers and IPP device URI options. CUPS is available at:

http://www.cups.org/


CUPS provides a portable printing layer for UNIX®-based
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 ("IPP") as the basis
for managing print jobs and queues. The Line Printer Daemon
("LPD") Server Message Block ("SMB"), and AppSocket (a.k.a.
JetDirect) protocols are also supported with reduced
functionality. CUPS adds network printer browsing and PostScript
Printer Description ("PPD") based printing options to support
real-world printing under UNIX.

CUPS includes an image file RIP that supports printing of image
files to non-PostScript printers.  A customized version of GNU
Ghostscript 7.07 for CUPS called ESP Ghostscript is available
separately to support printing of PostScript files within the
CUPS driver framework.  Sample drivers for Dymo, EPSON, HP, and
OKIDATA printers are included that use these filters.

Drivers for thousands of printers are provided with our ESP
Print Pro software, available at:

Changes in CUPS v1.1.21:



	
- The scheduler did not separate Digest authentication
 	parameters with commas (Issue #882)
 	
- Fixed some problems with image printing to custom page
 	sizes (Issue #891)
 	
- Removed the remaining scheduler code that did not use
 	the "close-on-exec" file descriptor flag to speed up
 	program invocations (Issue #890)
 	
- The "lpr -r" command removed the print file even if it
 	was not printed. It now only removes the file if the
 	job is successfully created (Issue #886)
 	
- Revamped the custom page size orientation fix
 	(Issue #127)
 	
- The lp, lpq, lpr, and lpstat commands now report when
 	an environment variable is pointing to a non-existent
 	printer instead of just saying "no default
 	destination" (Issue #879)
 	
- Queue names with 2 periods (e.g. "printer..2") were
 	not supported (Issue #866)
