Okay, I seemed to have solved the problem, although I am still not
certain what the cause of the problem was, at least I got bnetwork
printing up and running again.

What I did was to open the CUPS configuration dialog and delete the
printer. Then I let CUPS  discover what printers I have on the network.
Then I re-installed the printer and viola... it is printing again. I had
to do this on each computer and so far...(knock on wood) everything
seems to be back to normal.

I have no idea why this happened. In any event I want to thank Rick &
Ted for the help and suggestions which I have made note of in the event
of any future printing problems.

meanwhile I'll chalk this one up as some sort of unidentified glitch.
