The <DefaultPrinter ...> ... </Printer> tags in printers.conf are absolutely correct and not the cause of the problem. It is also correct that when you set the system's default printer with any printer setup tool that then the entry in printers.conf gets a <DefaultPrinter ...> opening tag.
Problem can be that somewhere else a default printer is set, for example ina ~/.cups/lpoptions file in your home directory or in an /etc/cups/lpoptions file. Please check these files and remove any unwished default printer choices. It is also possible that applications track a default printer by themselves or simply pre-select the printer used last within the application. AFAIK LibreOffice even tracks the las-used printer in the documents, making the "default" printer being selected per-document. ** Changed in: cups (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/1328798 Title: Setting default printer does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1328798/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
