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 Desktop Bugs, which is subscribed to gnome-settings-daemon in 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 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
