Great!.. Thanks for the tip, removing ulpt was enough for me. For the
2110, I can print via hpoj, and sane detects and can communicate with
the scanner.

However I still have problems with scanning. I just get an I/O Error.
Debug shows it's communicating, and the printer status displays
scanning, but nothing comes through. When it cancels it also resets the
scanner which shows it's communicating ok.

Some errors are also showing for me in mpt soon after ptal starting up,
which may be the problem although it doesn't affect printing. I'll
follow it up on the mailing list.

It's good to hear that it's working ok with your PSC 2170.
