The 1.1.2 release of the Common UNIX Printing System ("CUPS") is
now available for download from the CUPS web site at:
CUPS 1.1.2 fixes several small bugs as well as some build and
security issues that have been identified by CUPS users.
Binaries for several platforms are 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
filters.
Drivers for over 2300 printers are provided with our ESP Print
Pro software, available at:
http://www.easysw.com/printpro

Library General Public License. Please contact Easy Software
Products for commercial support and "binary distribution"
rights.
Changes in v1.1.2 include:
- Makefile/configure fixes
- RPM spec file and EPM list file fixes
- The cupsTempFile() function now uses a different
algorithm for generating temp files and "reserves"
them to avoid possible security exploitation.
- Now use /dev/random (if available) to seed the random
number generator for certificates.
- The /var/spool/cups and /var/spool/cups/tmp directories
were incorrectly owned by root; they are now owned by
the filter user, typically "lp".
- The scheduler now resets the permissions on the spool
and temp directories as needed to match the filter
user.
- Now expose ppdCollect() as an externally callable
function.
- The image filters now support filtering from the
standard input.
- The imagetoraster filter now collects all printer
options and job patch files and applies them to the
page header as needed.
- Added format and banner options to LPD backend.
- The send-document operation didn't start a job
immediately when last-document was true.
- The set-job-attributes operation didn't correctly
replace the current job-hold-until value.
- Removed the option wrapper code from ppdEmit() and
friends since it caused problems with Ghostscript
and many PS printers.
- Was setting TZ environment variable twice for job
filters.
- Added syslog logging in cups-lpd to aide in
debugging problems.
- The HP-UX parallel port backend did not list the
available parallel ports on some systems (printf
calling problem...)
- The lp and lpr commands overrode user options if
-d/-P were specified after -o.
- The scheduler would crash with a */* filter.
- Added support for a "default" filter for unknown file
types. The example provided in the mime.types and
mime.convs file prints unknown files as if "-oraw" was
specified for the job. This functionality is disabled
by default.
- The "compatibility" mode fix for older backends did not
work for smbspool. Added a workaround for it.
- The HP-GL/2 filter didn't perform the right pen scaling
with some files and the "fitplot" option.
- New Software Performance Specification document that
describes the memory, disk, and CPU usage of all the
CUPS software.
