I'm writing a windows app which sends data to the parallel port but because its pre-emptive there can be extreme latency in the timing.

AVR Mega644 is indeed sensitive to the SPI clock irregularities while being programmed.

I believe the OP wasn't talking about SPI. But with SPI you are right.

What else is the PC parallel port can be used for if not for the simulation of the SPI or I2C by bit banging?

I keep the 14-year old PC with Win98 exactly for this purpose: it is often the quickest way to get something to work.
