Seems obvious enough to me. CUPS on bpi54 was only listening to loopback (localhost), but Gene wanted to print through it remotely. So he had to make it listen to the network instead. My questions would be: 1) Can you put *both* Listen lines in, to keep loopback working? 2) Failing that, can you use 0.0.0.0 as the Listen address, to listen on all interfaces? That's the normal convention.
