Cudos to my wife: Here is a more detailed and accurate description of the issue:
Preset: Printer is installed on Ubuntu 18.04 Turning on the printer and printing any document -> works Putting notebook into suspend, after wakeup printing a document -> not printing Mitigation: - reboot printer - reinstall printer software After printer suspended (usually after 5 mins), printing a document -> not printing After manually waking up the printer from the display and printing a document -> not printing In all cases of not printing: If the printer queue was held, resuming from the GUI (both methods, from Settings and the Additional printer settings queue view) the queue goes into printing status and reverts to held. If the printer is freshly rebooted, starting a held queue leads to printing the document. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1768741 Title: hplip does not wake up printer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/hplip/+bug/1768741/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
