Print services are broken: Fedora and Debian

I'm currently unable to print from Qubes using either fedora-30,
debian-9 or debian-10 templates.

In debian-based vms, when I run 'system-config-printer' I get a 'failed
to connect to server' error.

In fedora, there is no longer any 'system-config-printer' command and
when I run 'gnome-control-center' it segfaults.

In neither environment can I browse to 'localhost:631' cups server. I
don't recall having such a problem accessing printers from Qubes in the
past. To me, this looks like Qubes has done something un-announced to
suppress print services.

Printing works on Debian 9 here as well as system-config-printer. I see
cupsd listening on 631 (and cups-browsed on UDP 631). I have a locally
attached USB printer and all updates applied from Qubes current + Debian
oldstable.

Yes, works fine for me in all Debian, including vanilla 10.
Have you made sure that cups is running?

unman:

Could it be kernel related since it's across all your templates? I'm
running 4.19.47-1 from testing a couple months ago.

That's odd. I don't recall having to enable 'cups' Qubes service, but
that resolved it.

The printing doc doesn't mention 'cups' Qubes service either.... Shrug!
It probably shouldn't be listed as 'external' and should be better
maintained.

I never had to specifically enable cups Qubes service, but printing works with Debian 9.

Best
