I'm not referring to server setups.  If you look at the lpt(4) manpage:

     /dev/lpt0    first interrupt-driven parallel port device
     /dev/lpa0    first polled parallel port device

When configuring cups with a parallel printer, it lets you choose "Parallel
(polled)" or "Parallel (interrupt driven)".  Choosing the later caused
system lookups (or something weird) last time I tried... and I was suggested
to use polled.

Performance problems?  Don't think so.

Ah, ok.
