One correction: I don't believe EPP requires (or uses) an IRQ. ECP
definitely does, but I'm pretty sure EPP doesn't.
Most high-speed peripherals that I've encountered work fine with the port
set to EPP in CMOS, but I have had problems with systems in general with
the parallel ports set for ECP, so I avoid using it.
