ECP is intended for parallel port storage devices, so if you have none
of those, EPP is the safest bet.

EPP also allows for burst transfers of data - only interrupting the CPu
when the transfer has finished.  A similar transfer using SPP would
interrupt the processor for every byte transferred, making it much
slower.

As an aside, my Brother HL8 laser has hysterics if ECP is set in the
BIOS.  I had to revert to EPP before all was sweetness'n'light again.
