  I had a similar experience with a 697C a few years ago.  I found that
when it was connected to lpt0, there were only 4 interrupts per second
being generated, which yielded a data transfer rate of 4 cps, causing
print jobs to require near-geological times.  By comparison, an HP
Laserjet II generated over 10,000 interrupts per second on the same
device during a transfer.  The solution was to switch the 697C to lpa0,
the polling device.
