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.
