The 1.0.2 release of the Common UNIX Printing System
("CUPS") is now available for download from the CUPS web site
CUPS 1.0.2 is a bug fix release. It also adds automatic page
size selection to the HP-GL/2 filter.
The Common UNIX Printing System provides a portable printing
layer for UNIX® 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 1600 printers are available in our
ESP Print Pro software.

automatically when the "fitplot" option is not used.
- The cancel-job operation was expecting a resource name
of the form "/job/#" instead of "/jobs/#"; this
prevented the cancel and lprm commands from working.
- The backends didn't log pages when files were printed
using the "-oraw" option.
- The authorization code did not work with the Slackware
long shadow password package because its crypt() can
- The chunking code didn't work for reading the response
of a POST request.
- cupsGetPPD() now does authentication as needed.
- The N-up code in the PostScript filter didn't work
with some printers (grestoreall would restore the
default blank page and device settings).
- The N-up code in the PostScript filter didn't scale
the pages to fit within the imageable area of the
- Wasn't doing an fchown() on the request files. This
caused problems when the default root account group
and CUPS group were not the same.
