I followed the discussion about ieee1284 nibble mode here a while.

I knew my printer (Minolta PagePro 6L) must identify itself somehow because
windows is able to detect (and name) it.

But parport_probe fails with the same problems Andrea reported.
So I had a look at Andrea's patch and disabled the "error line indicates end of
data" check in parport_ieee1284_read_nibble and, voila it worked.

But also the idlen in parport_probe is calculated wrong. We don't need to
substract 2 because the idlen does not include the two idlen bytes...

With these two changes parport_probe works here.
I get not status readback from the printer with cat dev/lp0 but I think that's
because the printer does not support it...
