Nah, I'm talking about re-inventing the computer here, not throwing
together a device intended to be mistaken for a suitcase bomb.

Using the printer as a coprocessor is a rather moot idea, unless you
also include a scanner in the system design; there's no other way to get
data from the printer back into the computer.

You /could/ of course make a PostScript printer do some raytracing
entirely on its own. But I was a bit disappointed by the computing
performance of the printer I once used for generating a printout of the
Mandelbrot set, so I'll probably not pursue this project any further...

Also, I guess we won't get real-time raytracing capabilities out of a
printer anytime soon ;)
