Apparently current update of hplip has disabled hplip like recent two updates before this ?
However hplip was working pretty good with LibreOffice before current update.
It seems to be the same reason like it was last time.
Now I try re-install with :
sudo eopkg it --reinstall hplip
This did not help - after gnome-settings-printer announces "printing is running" - then comes
announcement shortly after with "printing has been stopped". No further reason at all.
