try putting the printer in interrupt-driven mode

for 2.2.x kernels

echo 7 /proc/parport/0/irq
(where '7' is the IRQ assigned to the port in the BIOS)

for 2.4.x kernels its different

modprobe parport irq=7 io=0x378
(I think thats the right module, either that or maybe its parport_pc..)

7 is the most commonly used IRQ for parallel ports in my experience.

also be sure nothing else is using the port

lsof | grep /dev/lp
