Mike, I'm basing my remarks on your comment 
that you can hit "engine speed" on a 133 MHz 
machine, while my prints clearly tax the hell 
out of a 350 MHz machine.

To me, it seems just as likely that Epson driver 
processes the image file piecemeal, during those 
short print-head pauses.

There may well be other factors at work that
neither of us have thought of.

I think your math (re. data rates for
USB and parallel) are basically sound,
and my reaction to Tim's post was pretty
much the same as yours, based on similar
calculations.
