I used Max on a old mac with serial ports to drive a imagewriter and a  
NEC 24 pin printer. Though studying the manuals I never managed to  
freely move the head around - it would only do something after  
carriage return. I did intend to write characters, so maybe I didn't  
discover graphics protocol. The NEC had a parallel port and worked  
fine with a parallel to serial adapter I got cheap on ebay.

You might want to look for a pen plotter, too. HPGL is simple to do  
and you can move around with great precision, control speed, and with  
some you even have 2 axis. Plus "PD" is the pen down command ;) Common  
models that don't crowd your space to much are HP 7574a and Roland dxy*
