Yes, I tried turning it off and on again, and also rebooted the
computer. No joy. I didn't try phasersmart.com yet.

My googling turned up localhost:631 and I was amazed. There are all my
printers! Cool tool! However, after poking around I found nothing that
would solve the problem. Interestingly, this is what it says for the
printers that I have installed for this print device (it says the same
thing for all of them):

Xerox Phaser 7400DN PPD3		Local Raw Printer
Processing - "The printer is in use."

>Can you print to it from a different computer?

I haven't tried that yet. My old printer is sitting here turned
off, and it might get me by, but sooner or later I have to get this
printer working from the new computer, so I'm spending my efforts on
that first.

I am wondering if there is a config file somewhere that CUPS uses to
get printer data. Perhaps I can manually modify it or delete it.
