Interrupt storm detection

Hi

I have a problem printing.  The data rate through my parallel port
to my printer makes the kernel think that lpt0 is storming at between
40k-49k irqs per second.  Is there a way to tell the kernel to
ignore certain interrupt sources or to raise the per-second throttle
value?  I've only found hw.intr_storm_threshold which I assume is
the number of interrupts from a source before an interrupt arives
from another source.  I've set this to 2000 to make the printing
work, but now I'm not sure if this will protect from a real interrupt
storm.
