When I originally replied I didn't notice that it was going to you directly
instead of to the list until after I had sent it.  I'll see if the
sourceforge folks can do anything about this.  In the meantime I'll just use
"reply to all" to make sure that it goes to the list.  I much prefer getting
mail through the list rather than directly, because then it also goes to my
personal (home) e-mail account and reduces the chance that it gets lost in
my inbox at work.  :-)

Bummer.  Those were the easy solutions.  :-)

I looked at your lsmod output again to see if there were other drivers (like
lp) hogging the parallel port, and I didn't see any.

Try this, and give me the output:
	cat /proc/parport/0/autoprobe
If your peripheral doesn't show up, then see what other port numbers (1, 2,
etc.) are in the parport directory, and try substituting those one by one
for "0".

Is your peripheral by any chance connected to a switchbox or other
"pass-through" device, such as a Zip drive?  It probably won't work in these
situations.

Is the parallel port enabled in your BIOS/CMOS setup?  Ideally it should be
set to "ECP" or "bidirectional", although the drivers currently don't use
the enhanced functionality.

Are you able to print just by dumping text or PCL data to /dev/lp0 (or lp1,
etc.), without loading ieee12844pp.o?  If your computer dual-boots with DOS
or Windows, can you print there?

What is the output from:
	cat /proc/ioports
	cat /proc/interrupts
This is to see if there's an I/O port or IRQ conflict with something else in
your system.
