When wanting to print thru /dev/lpt0 the kernel now starts to complain about interruptstorms. Something I can imagine, since printing can generate > 1000 ints/sec. Problem is that the current document (500k) is now printed at 100 interrupts/sec. That's going to take some time.... How do I prevent this from happening? Thanx, --WjW
