Sorry, I think I don't understand (or you don't understand :)

Your server has interfaces. lo, eth0, whatever.

You want your print-server to be usable from the LAN. That LAN is
attached to e.g. eth0. So packets from the LAN will arrive at eth0.

Also, you might want to manage your server locally, i.e. access
it via localhost:631 on the server itself -- packets will arrive on the
lo-interface.

So you could either specify Listen-directives in cupsd.conf for
the IP-addresses of those two interfaces, or just let CUPS listen
on all interfaces, as it does now.

This is not related in any way to "over Internet".


Again: You don't want to change the listening address. 0.0.0.0 is fine.
But if you have some really strange reason you haven't told us about, check
