Re: HP ScanJet Plus + Debian 2.0 (fwd)
Ray, Thanks for the input. Some things are making a lot more sense
here. I'll make comments below.

DOS? Whassat? Winders? Whassat? *smirk* Seriously, though, I'm
afraid that I can't test this scanner under either DOS or Windows,
since I ditched all of that over a year ago (ain't it great to be
MS-Free? visit www.i-want-a-website.com)

I noticed before that it was not explicitly listed, but I was hoping
that some of the newer drivers might be backward-compatible.

I'll look into getting this app. Do you know off-hand where I can get
it? If not, I'll do a web-search when I get a chance. :)

The I/O card is actually a multi-I/O..
EIDE+Floppy+Serial+Parallel. All are enabled and working properly.
Yes, I have had a dot-matrix printer working on the parallel port
before. This time, however, I modified my /etc/printcap to contain
only one remote-printer definition pointing to my other linux box.
Thus, lpd should not be trying to use this parallel port and should
not be conflicting with the scanner software or device.

I'm aware of the SCSI emulator kernel module... I forgot to check that
a moment ago while rebuilding my kernel, though... I can go back and
try that tomorrow. Also, I *do* have a SCSI->Parallel adapter kicking
around which was given to me with the scanner. I also have a SCSI
card floating around which is known to work with the NCR-5380 module.
I suppose that I could add those two components, but at first, this
seemed like overkill... perhaps now it is the way to go.

This makes perfect sense now. The last time that I saw 'pnm:' though,
was with rvplayer5.0 in 'pnm://www.ithaca.edu/radio/vic/viclive.ram'
or something like that.

Forgive me for not chopping out all the extraneous info here... it's
in the interest of my time ;-)
