Common UNIX Printing System 1.1.21

[Michael Sweet]

The 1.1.21 release of the Common UNIX Printing System ("CUPS")
is now available for download from the CUPS web site at:

     http://www.cups.org/

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 provides a portable printing layer for UNIX(r)-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 v1.1.21 include:

	- The scheduler did not separate Digest authentication
	  parameters with commas (STR #882)
	- Fixed some problems with image printing to custom page
	  sizes (STR #891)
	- Removed the remaining scheduler code that did not use
	  the "close-on-exec" file descriptor flag to speed up
	  program invocations (STR #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 (STR #886)
	- Revamped the custom page size orientation fix (STR
	  #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" (STR #879)
	- Queue names with 2 periods (e.g. "printer..2") were
	  not supported (STR #866)

Enjoy!
