I have already found a solution for this and applied it upstream (1.27.5, already in Grrovy).
The problem is that near midnight, for the log rotate cups-browsed is stopped and restarted. Stopping cups-browsed makes the cups-browsed- generated print queues getting removed and when re-starting cups-browsed afterwards they are generated again. This causes the notifications. My approach is to let cups-browsed not remove the queues on shut-down, on re-start cups-browsed connects to these queues again (as I have designed cups-browsed to cope with crashes) and so no queue-creation happens. Zdenek Dohnal from Red Hat suggests modifying gnome-settings-daemon to identify queues coming from cups-browsed and not notifying then. See https://github.com/OpenPrinting/cups-filters/issues/241 Marking as fixed as my approach has made it into Groovy already. ** Bug watch added: github.com/OpenPrinting/cups-filters/issues #241 https://github.com/OpenPrinting/cups-filters/issues/241 ** Changed in: cups (Ubuntu) Status: Triaged => Fix Released ** Package changed: cups (Ubuntu) => cups-filters (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1869981 Title: Printer notification every day at midnight To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups-filters/+bug/1869981/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
