Seb, in any application with GTK printing dialog try to print with a custom paper size:
Run the command cupsctl LogLevel=debug File/Print, in dialog select printer on "General" tab, switch to "Page Setup" tab, click on paper size drop down and choose "Manage Custom Sizes ...". Create a custom paper size. Now choose the newly created custom size and print. In /var/log/cups/error_log You will find a line like D [13/Jul/2012:19:24:49 +0200] [Job 626] argv[5]="InputSlot=Default PageSize=Custom.Custom.595.28x841.89 Duplex=None PrintoutMode=Normal PrinterResolution=FromPrintoutMode number-up=1 job- uuid=urn:uuid:bd2f3351-a345-3abb-63d9-ea13d11a8f39 job-originating-host- name=localhost time-at-creation=1342200218 time-at- processing=1342200289" Note the "PageSize=Custom.Custom.595.28x841.89" in the line. For some programs (like Firefox for some users) it can even happen with regular paper sizes, but with custom sizes it occurs for sure. I have tested with Thunderbird on up-to-date Precise now and reproduced it as described above. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gimp in Ubuntu. https://bugs.launchpad.net/bugs/998156 Title: GTK Print dialog sends broken custom page size attribute: "PageSize=Custom.Custom.<width>x<length>" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/998156/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
