I tried rebooting without use.
On a Ubuntu laptop in the same network, through Wi-Fi, the problem does not exist.
I have read this topic and I tried to follow the steps in there:
$ lpinfo -v network http network ipp network beh file cups-brf:/ network https network socket network lpd network ipps file cups-pdf:/ direct hp network smb direct hpfax network dnssd://Canon%20MG4200%20series._ipp._tcp.local/?uuid=00000000-0000-1000-8000-84BA3BB0352F network ipp://Canon%20MG4200%20series._ipp._tcp.local/
Please tell me which other commands to run and which commands to post the output from.
I have ghostscript-9.53.3-2 installed.
I am afraid to try to uninstall the printer because I wish to have the scanner functional at least.
