I find that a simple modification to lpa.c (or lpt.c, depending on
which you use) fixes the probing problem.  Look for a line in the
probe routine that looks like:

	mask = 0x1e;

and replace it with:

	mask = 0;

This shuts off the probe of the parallel port's control port.  Probing
the control port doesn't work if your printer and/or printer cable
has some control lines permanently set high or low.

I would vote for getting rid of the control port probe entirely.
Probing the data port should be sufficient, shouldn't it?
