Printing problem with cups-1.6.4-2.fc19

[Joachim Backes]

Hi all,

having a problem since having updated to

cups.x86_64 1:1.6.4-2.fc19
cups-filters.x86_64 0:1.0.38-2.fc19
cups-filters-libs.x86_64 0:1.0.38-2.fc19
cups-devel.x86_64 1:1.6.4-2.fc19
cups-filesystem.noarch 1:1.6.4-2.fc19
cups-libs.i686 1:1.6.4-2.fc19
cups-libs.x86_64 1:1.6.4-2.fc19

I use some Libreoffice documents with gray background.
I'm printing to a Samsung ML-1660 B/W printer. Since that cups version
update, the gray parts of my document are signifinatly darker printed
than with the previous cups version, and the gray areas are not smoothly
printed.

I have the impression that the color management now fails in cups.

Anybody has similar problem? All comments are welcome.

Kind regards

Had you set a colour profile for the printer?

It sounds more like it might be a filter/driver problem than a problem
in cups proper. Could you try downgrading cups-filters and
cups-filters-libs and see if that makes a difference?

No, I didn't.

Because of dependencies I hat to downgrade totally the cups software:

Great! Now it should be possible to upgrade each of those (ghostscript,
cups-filters, and cups) one by one to see what makes the difference.

1. First update:
-----------------

Updating:
 cups                  x86_64       1:1.6.4-2.fc19          updates
  1.3 M
Updating for dependencies:
 cups-devel            x86_64       1:1.6.4-2.fc19          updates
  126 k
 cups-filesystem       noarch       1:1.6.4-2.fc19          updates
   88 k
 cups-libs             i686         1:1.6.4-2.fc19          updates
  348 k
 cups-libs             x86_64       1:1.6.4-2.fc19          updates
  346 k

No update for cups-filters-libs-1.0.38-2.fc19.x86_64 and
cups-filters-1.0.38-2.fc19.x86_64

*Result: Document is still printed well!*

2. Trying to update cups-filters* from updates-testing repo:
--------------------------------------------------------------

================================================================================
 Package               Arch       Version             Repository

================================================================================
Installing:
 cups-filters          x86_64     1.0.40-2.fc19       updates-testing

     replacing  ghostscript-cups.x86_64 9.07-15.fc19
Updating:
 cups-filters-libs     x86_64     1.0.40-2.fc19       updates-testing
   90 k

*Result: Bad print output*

So, cups-filters... seems to be the culprit.

Kind regards

Great. Thanks for narrowing this down. I wonder if we can narrow it down
even further...

Could you please try cups-filters-1.0.39-1.fc19 from koji?
http://koji.fedoraproject.org/koji/buildinfo?buildID=469163

We have enough information now to file a bug report against cups-filters
in Fedora so we can track this properly. Would you mind doing that?
https://bugzilla.redhat.com/

Thanks,
Tim.

Tim,

still no good printing with this cups-filters
(cups-filters-1.0.39-1.fc19.x86_64.rpm and
cups-filters-libs-1.0.39-1.fc19.x86_64.rpm)
