The 1.1b5 release of the Common UNIX Printing System ("CUPS") is
now available for download from the CUPS web site at:


CUPS 1.1b5 is the final beta release for CUPS 1.1.  It provides
many bug fixes, documentation updates, and a few enhancements to
the job-hold-until support.  Binaries for several platforms are
also available.

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 also includes a customized version of GNU Ghostscript
(currently based off GNU Ghostscript 5.50) and an image file RIP
that are used to support non-PostScript printers.  Sample
drivers for HP and EPSON printers are included that use these

Drivers for over 2300 printers are provided with our ESP Print
Pro software, available at:

Changes in v1.1b5 include:

	- Documentation updates.
	- The pstoraster filter didn't compile without the JPEG
	- The cupsd server didn't support the HTTP OPTIONS request
	- Dropped the "CLOSE" method supported by the cupsd server.
	  (not defined in HTTP specification)
	- Makefile/configure script fixes.
	- Missing the job-restart template.
	- Added IPP test suite for testing.
	- Missing IPP documentation from binary distributions.
	- Fixed multiple-document handling code when last-document
	  not specified.
	- Added more checks to IPP requests to prevent bad requests
	  from getting through.
	- Not all of the Ghostscript error output was being sent to
	- The PostScript filter now added PJL commands to set the
	  job name and display string, if supported.
	- The scheduler would crash if the browse socket could not
	  be bound. Now disables browsing if port 631 (reserved for
	  IPP) is being used by a misbehaving daemon.
	- The USB backend now looks for the older Linux 2.2.x USB
	  printer device filenames as well as the newer ones.
	- The IPP backend now uses the UTF-8 charset exclusively,
	  since apparently only CUPS handles more than US-ASCII and
	- Wasn't quoting ( in PostScript banners...
	- Send-document requests with no document-format attribute
	  could cause cupsd to crash.
	- Old jobs in the spool directory might cause cupsd to
	- CUPS now supports all of the recommended job-hold-until
	  keywords as well as name values of the form "HH:MM" and
	- Added placeholder pointer for TLS encryption to the HTTP
	  connection structure.
	- Fixed the "fast poll" bug reported by DISA - the
	  status pipe wasn't being closed for multi-file jobs.
	- Revamped put_params code in pstoraster to fix bitmap
	  allocation bug with FrameMaker output.
	- Ripped out filename, etc. code from pstoraster as it
	  is a potential security hole.
	- Added support for RIP_CACHE environment variable in the
	  new pstoraster.
	- Fixed USB device filenames for Linux; now support new
	  pre-2.4 devices (/dev/usb/lp#) and 2.2 devices
	- Fixed accept-jobs crash with classes.
	- Didn't include dot-matrix EPSON drivers in previous
