Aha!!!! Got it, geany evince okular etc can now print from bpi54! Removing

made the localhost:631/printers on this machine show up in FF on bpi54, all

Any explanation?

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.

Close, I wanted to be able to print from the bpi from any app on the bpi that had a print this option. Now I can.

My questions would be:

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

No, that kills the cups ability to query the network even with the Server named in client.conf. It even logs it as a failure, on the bpi5 but doesn't say why.

2) Failing that, can you use as the Listen address, to listen on
    all interfaces?  That's the normal convention.

Untried, so can't say. And I've not read far enough to see that as an example.

Thanks Greg.

Cheers, Gene Heskett.
