alciregi, I have a similar issue. Reference the bug below. https://bugzilla.redhat.com/show_bug.cgi?id=1812515 Try the following. Set up a root password. On the terminal use (sudo passwd). Enter a pass word and then verify it. Close the terminal. Open your browser and go to localhost:631 then click Administration. Then click Add Printer. Log into CUPS with User = root and your root password you just set up. You may need to click Add Printer again. Your printer should be listed. Select your printer and Continue. Follow through with the rest of the setup procedure to see if CUPS can directly setup your printer. If not you should should file a bug report at Bugzilla and an Issue at gitlab-gnome. Have a Great Day!
