Just a wild guess: Maybe avahi-daemon is involved somehow? For me at least these annoying messages seem to have stopped completely after throwing out the avahi-daemon service (for other reasons).
So you may try this: systemctl disable avahi-daemon.socket avahi-daemon.service If it helps, do this: systemctl mask avahi-daemon.socket avahi-daemon.service systemctl stop avahi-daemon.socket avahi-daemon.service -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1725955 Title: "Printer added" notification To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-settings-daemon/+bug/1725955/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
