Using the web-interface of CUPS I could add my printer seamlessly and
even print a test page. So thanks! However, as mentioned in [1], the
web interface responded super slowly which was the reason to use
system-config-printer and gnome-control-center in the first place.
After the fix the web-interface now runs smoothly.
However, gnome-control-center still `Failed to add new printer' and
system-config-printer still prints the error message I mentioned before.
As before it adds the printer but refuses to print a test page saying
‘There was an error during the CUPS operation: 'No such file or
directory'’.
Nevertheless, I found that it is possible to print a PDF document from
evince on the very same printer that I added using
system-config-printer. So the problem seems to lie within
system-config-printer (and not CUPS) searching the right PATH for the
Epson filter. Additionally, gnome-control-center does not seem to work
at all in that regard because I did not manage to add the printer with
it.
I am happy now since I am able to print but maybe it is worthwhile
investigating this issue with gnome-control-center within the
core-updates-frozen branch. Because this would be the first place to
try to add printers for new Guix users that use Gnome. I would be happy
to help although I can probably only try to reproduce this issue on
core-updates-frozen.
Best
Daniel
