It currently takes about 5 minutes to transfer a 20MB file to my printer
which has 64MB of memory.  Printing starts within 5-10 seconds of the upload
being completed.  If the parallel port is in interrupt mode, CPU is pegged
to 100% the whole time.  In polled mode, CPU usage drops, but the printing
time doesn't decrease (and the ``parallel'' process is running the whole
time).  That's what made me think that the parallel port is probably the
bottleneck.
