In order to ensure CUPS-PDF is running with the required root privileges you have to make 'root' the owner of the cups-pdf backend and set the file permissions of the backend to 0700 (root only)</a> -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1479143 Title: Print UI hangs on launch and will not close To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/system-config-printer/+bug/1479143/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
