slow to handle data that the computer can throw at it.  What happens is
that using the parallel interface, the computer gets the data and then no
pages come out.  I suspect that it's because the printer loses the end
showpage command.  I have adjusted the  strobe rate using tunelp, which
helped with small jobs, but the larger jobs still get lost.  I figure with
a serial connection, it can handle the slower data transmission.
