Your printer port is on IRQ 7, which is the "garbage" interrupt
for all unrecognized interrupts, and you have some other device
that is generating unexpected interrupts that are going to IRQ 7
and flaking out the printer driver; probably a sound card with
an open collector microphone connection, or a video card that's
spitting vertical retrace interrupts onto IRQ 2.
