: Are you using the interrupting parallel port driver?  (lpt0).  If so, then
: use the polled parallel port driver.  AFIAK, no i386-based Unix has a
: working interrupt-driven parallel port driver (I'm pretty sure the Linux
: and FreeBSD ones are all polled).  If I'm wrong, I'd love to hear about
: it!

FreeBSD's is inerrupted by default - the linux one you may switch to
interrupted i think - and at the university we have a printer connected to the
inerrupted lpt port (FreeBSD) - here at home it only works with polled mode
using my hp deskjet 600 (maybe a bogus lpr port on the card) - but i can use
the parallel port tcp/ip mode of FreeBSD fine using interrupted mode - thus i
think it's maybe worth looking into the FreeBSD lpt driver
