My questions would be:

1) Can you put *both* Listen lines in, to keep loopback working?

The cupsd.conf(5) man page says: "Multiple Listen directives can be
provided to listen on multiple addresses."

My results seem to indicate otherwise.

I don't think that you even showed anything. The only test you
should do about that is to try to connect to the port, e.g. with
telnet (or nmap can probably tell you). If the connection isn't
immediately refused, then the Listen directive is OK.

For instance:

zira:~> telnet localhost 631
Trying ::1...
flushoutput character is 'off'.
Connected to localhost.
Escape character is '^]'.

Fine. And you can try the same thing from a different machine on
the network, replacing "localhost" by the IP address of the server,
e.g. from another machine on my network:

$ telnet 631
telnet: Unable to connect to remote host: Connection refused

because my CUPS server just has

Listen localhost:631
Listen /var/run/cups/cups.sock

If the connection is accepted with telnet by using multiple Listen
directives, then the Listen configuration is correct. If you can
see any other issue related to the printers, then the problem is
due to something else.

I'm confused. There is not anything wrong with this machine as a Server.
ALL of this muttering and bitching has been because bookworm clients did NOT work. buster clients work great.

How many times do I have to say it is/was a CLIENT problem that only exists for BOOKWORM clients. The elephant in the room that most have ignored.

What I have done, on the BOOKWORM CLIENT works, but we still don't have a clue why that is so.

That said i've dl'd the src from cups, which is broken by not being in a state that will even autogen. So I dl'd the obviously much later src.zip from Mikes new openprinting site. The zip is about 250% the size of the apple tar.gz. Its complete and only needs one argument to configure, with-tls=no. Then it builds and passes a make test, but I've not installed it on this machine.

The debian code appears to be the Apple src.
What I intend to do is move the openprinting version 2.4.5 to one of the bpi's, see if it will build there, and install it on the bpi to see if that works. But I'm just one, and there is only so much I can do in a day.
