The first command outputs local print queues; cups-browsed should form these from what CUPS tells it with, essentially, the second command. It obviously isn't doing that. BTW, printing should still be available to you with 'lp -d...'. Also, if you stop cups-browsed, the dialogs of LibreOffice and Qt apps (and maybe GTK apps) should list printers and print queues. > > in cups-browsed.conf and taking a look at a log wouldn't be a bad > > idea. > > Fri Dec 6 11:00:58 2019 Removing entry B... > (ipps://host.local:631/printers/B...) and its CUPS queue. > Fri Dec 6 11:00:58 2019 Recording printer options for B... to > /var/cache/cups/cups-browsed-options-B... > Fri Dec 6 11:00:58 2019 Unable to get PPD file for B...: The printer > or class does not exist. > Fri Dec 6 11:00:58 2019 Unable to load PPD from local queue B..., > queue seems to be raw. > Fri Dec 6 11:00:58 2019 ERROR: Failed disabling printer 'B...': The > printer or class does not exist. > > I guess that explains why the printer is no longer active, but what > changed from the prior version of cups-browsed?

In the past I have stopped cups and cups-browsed and removed the files in /var/cache/cups, checked that there aren't any files in /etc/cups/ppd and that /etc/cups/printers.conf is empty, then restarted the cups and cups-browsed services. If you do not get anywhere, please report it upstream at https://github.com/OpenPrinting/cups-filters/issues perhaps after reading https://github.com/OpenPrinting/cups-filters/issues/124 Regards, Brian.
