Hello Till: running /usr/share/system-config-printer/scp-dbus-service.py --debug did not provide any information when running or printing gnome-settings.
Nevertheless perhaps this other log might be helpful for you. I have taken it from runnig /usr/share/system-config-printer/system-config-printer.py --debug I'm uploading outpout as printer.log just in case this was useful BR ** Attachment added: "system-config-printer.py output" https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1202198/+attachment/3901655/+files/printer.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1202198 Title: gnome-settings daemon notifies as error an info message To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1202198/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
