Also affects Fedora 12.  Will handle as an update.

+++ This bug was initially created as a clone of Bug #531278 +++

This works on Fedora 10 with cups-1.3.10-5.fc10.i386.

It does not work with Fedora 11 and later with cups-1.4.1-4.fc11.i586.

Note the lack of "-Oc=0 -Om=0 -Oy=0" in the foo2hp2600-wrapper line!

I think is it because the XML using <arg_max>100</arg_max> and
<arg_min>-100</arg_min> (ref. foomatic-db/opt/foo2hp-AlignCMYK.xml)
doesn’t get translated to a (possibly depracated?) *.ppd syntax (HP-
Color_LaserJet_2600n.ppd).  But I could be wrong...

I note that the lx5000 and others are the same way...

This is a foomatic problem.

--- Additional comment from rick.richardson on 2009-11-02 16:37:46 EDT ---

So it is the interaction between cups and foomatic?  Because cups says

f11# grep "foo2hp2600-wrapper " /var/log/cups/error_log 
D [27/Oct/2009:06:28:04 -0500] [Job 3] Starting renderer with command:
"foo2hp2600-wrapper -z0   -b1  -p1 -m1 -s7   -d1 -Gdefault "

Note the lack of "-Oc=0 -Om=0 -Oy=0" in the foo2hp2600-wrapper line.

--- Additional comment from twaugh on 2009-11-03 06:09:39 EDT ---

The message comes from foomatic-rip.

--- Additional comment from rick.richardson on 2009-11-03 06:54:59 EDT ---

OK, it is foomatic writing into the cups error_log.  I think that foomatic would prepend "foomatic: ..." onto the debug message since it is writing to the cups error_log!!!!

--- Additional comment from twaugh on 2009-11-05 11:03:55 EDT ---

No, it isn't writing directly to the error log.

Reported upstream:
  http://bugs.linux-foundation.org/show_bug.cgi?id=399

Changing version to 11 as that is also affected.

Thanks!  (One line fix.)
