Apparently you have worked out the timing issues for the HP controller that wants to see paper moving at certain times. I'm curious what you've come up with.

Right now I've taken a LJII and stripped it down to just the fuser and drive stepper. I'm getting the stepper to run from a microprocessor, I have it running from an arduino, but am going to use a small AVR, probably a ATiny2313. I am planning on controlling the fuser lamp with a micro also, to give me adjustable temperature. Hopefully this will be better than the iron method, my results with that are mixed at best.
