cups 1.4.1 in ubuntu 9.10 defaults to duplex on everything. Setting manually to simplex does not fix.

See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=550575

Looks like it was fixed here. I added the patch and problem solved. Problem was the filter cpdftocps

https://launchpad.net/ubuntu/+source/cups/1.4.2-1

Alfred, is this bug fixed? (Did you get it with an update?) If so please close this bug, thanks!

It got already fixed in version 1.4.2-1 (both Debian and Ubuntu) from Nov 17, 2009, with my new cpdftocps filter.

Till, could you please try to push an update to karmic? I have an up-to-date karmic and the bug is still here.

The fix has been released only for Lucid.
The CUPS version on Karmic is still 1.4.1-5 with the DUPLEX and other bugs.
Can someone release an update also for Karmic?

nicolaasuni, note that the main task is for Lucid, and there the fix is released. For Karmic there is a subtask which I did not mark as fixed. I will post a Karmic package for testing soon.

OK. Thanks for the explanation, I was confused since the "Lucid" term is not mentioned.

SRU for cups in Karmic, fixing bug 407344, bug 487902, and bug 508731 uploaded, waiting for approval. debdiff attached.

Uploaded new version of the SRU to -proposed which also covers bug 447961. debdiff attached.

Accepted cups into karmic-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

The problem seems to bee fixed now. My first test file was printed properly on separate pages.

Any news? activating the single cups package from proposed didn't work for me, and I wouldn't like to load the full list. Thanks!

Romano Giannetti, probably your problem is caused by another bug and not this one.

Can you attach your /usr/lib/cups/filter/cpdftocps file and post the output of the shell command

dpkg -l | grep cups

Can you also provide an error_log as described in the "CUPS error_log" section of

https://wiki.ubuntu.com/DebuggingPrintingProblems

Romano, I had to install 4 packages from the proposed updates. (AFAIR)

This bug was fixed in the package cups - 1.4.1-5ubuntu2.2

    fix from Koji Otani for the following: (1) Fixed some memory leak;
    (2) pdftopdf now delays fetching a referenced object until when it is
    written to the output. This fixes memory hogging with N-up output
