RHBA-2007:0708 - Bug Fix Advisory

Topic

An updated foomatic package that fixes a bug and adds printer
identification strings is now available.

Description

Foomatic is a comprehensive, spooler-independent database of printers,
printer drivers, and driver descriptions. (The site
http://www.linuxprinting.org/ is based on this database.)

Foomatic provides utilities to generate driver description files and
printer queues for CUPS, LPD, LPRng, and PDQ from the database. As well,
foomatic makes it possible to read PJL-options out of PJL-capable laser
printers and take them into account when driver description files are
generated.

The package also includes spooler-independent command line interfaces to
manipulate queues (foomatic-configure) and to print files/manipulate jobs
(foomatic printjob).

This updated package fixes the following bug:

when using system-config-printer to create a new printer using a previously
imported PPD, selecting 'edit' from the printer list contextual menu would
cause the application to crash.

The underlying cause:

if a PPD file's CDATA section contains so-called 'high-ASCII' characters
(ie characters with an ASCII value above 128) foomatic treats the PPD as if
it were a UTF-8-formatted file, even if it is not.

The fix:

the xml_esc function in PPD.pm now checks the CDATA section of PPD files
and temporarily replaces any high-ASCII characters with a standard-ASCII
character (the question mark, '?').

The result:

system-config-printer no longer crashes when reading imported PPD files.
Consequently, new printers can be created with system-config-printer from
imported PPD files.

This updated package also adds printer identification strings for the
following printers:

• Epson Stylus Color 777
• Epson Stylus CX3200
• Epson Stylus C82
• Epson Stylus Photo 790
• Epson Stylus Photo R300
• Hewlett-Packard Business Inkjet 1100 Series
• Hewlett-Packard DeskJet 3820
• Hewlett-Packard LaserJet 8150 Series
• Hewlett-Packard Color LaserJet 4550
• Hewlett-Packard OfficeJet G95
• Oki Data IKPAGE 6e
• Samsung ML-1710

NB: these printers worked with earlier versions of Foomatics but threw 'no
match for USB device' or 'No IEEE 1284 match' errors when they were being
setup for use with system-config-printer.

The added printer identification strings don't change the functionality of
the printers under Red Hat Enterprise Linux. They do, however, stop the
errors from presenting and, in some cases, make setting up the printers for
use simpler.

All foomatic users should upgrade to this updated package, which resolves
these issues.
