What you could try is to edit the URIs in the /etc/cups/printers.conf file. Stop CUPS, edit the file and after that start CUPS.
You have to edit the URIs adding "<USER>@" before the host name. Turn ipp://cups.ncs.mcgill.ca:631/printers/mcgill_mono into ipp://jonall...@cups.ncs.mcgill.ca:631/printers/mcgill_mono Does this work for you? ** Changed in: system-config-printer (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/856776 Title: Cannot declare itself as another username with CUPS server To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/system-config-printer/+bug/856776/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
