I tried everything I know to add a printer, but I get authentication error when I use CUPS. The other way, system-setting/printers does not work either. I edited the cupsd.conf file, but no luck. I added my user ID to the lpadmin group, still no luck. It is a bit frustrating, because I had no problem adding a printer to Raspberry PI 4. Any help would be appreciated.
