I did it twice, the extra time to get the column headers. Splicing the two together...

Is this what it should be? Anything I should do? I guess it's not relevant to the current matter, but should cupsd be in the list twice?
As already noted, cupsd is listening on both ipv4 and ipv6.
It isn't important, but I would note there is an unnecessary service running on port 111. That would be rpcbind.
As time permits I'd check
systemctl status rpcbind
and
systemctl status rpcbind.socket
