SPP/EPP/ECP

Hihi,
I am not sure whether I am in the right section but anyway here's the question.

I read my motherboard manual and there's the section on parallel mode. There's the SPP, EPP, ECP and ECP+EPP mode. I was wondering what is the difference between them. If I have a printer connected to the parallel port, for the fastest printing speed, which mode should I be in. My default mode is SPP.

Here are a few infos on parallel port modes:

Cannot explain the difference...but maybe the above sites can help a bit.
The "fastest" mode is SPP, though, some devices (e.g. printers, scanners) sometimes produce errors or won't work at all.
These modes are only supported in WIN9x, not under NT (yet).

ECP requires a DMA channel I think.

Maybe another expert can provide you with more details...
