Dear All,

Is anyone having any luck using the HP PSC 500 all-in-one printer and scanner (or any other HP all-in-one on a parallel port) under Linux? If so, please can you tell me how?

The story so far:

Once upon I time, I was printing and scanning happily, using the hpijs back-end to CUPS and the hpoj back-end to SANE. Then scanning stopped working, apparently due to the bug described at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=339584. About three weeks ago, I decided to deal with this by migrating to hplip's hpaio back-end to SANE, but have had no joy.

Functionality seems to have steadily deteriorated since then, perhaps with successive upgrades to the SANE version in Debian Testing; at first, the scanner would freeze part-way through scans above a (low) critical resolution, then the scanner would freeze part-way through all scans, whatever the resolution, now SANE front-ends can't see the scanner at all.

I note in passing that the list of available devices in CUPS contains the line "hp no_device_found," and I'm having to get printing to work using "Parallel port #1" from this list, which I suspect means I'm, in some sense, bypassing hplip, even though I'm using "HP(HPLIP)" as the model/driver option.

I think this may have something to do with the following messages in syslog; maybe the first two lines represent two things happening in the wrong order? The first one seems to occur during loading of kernel modules, and the second on running of /etc/init.d/hplip start.

Any ideas are welcome.
