Comment 2 for bug 1768741

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.
