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 1: https://lists.gnu.org/archive/html/help-guix/2021-12/msg00010.html
