These don't mean that much to me and are probably nothing to do with
what we are investigating. They are likely harmless. I thought the
output might show a complaint that the program could not connect to
localhost:631.

This is the worrying bit. You have shown you have cups running but there
is no sign here that it is listening for any connection on 127.0.0.1,
which is localhost.

We need to see your /etc/cups/cupsd.conf. Please would you post it. Send
the contents of /etc/hosts too.

It does.
