Just a thought!

Hi.
What if, you took a surplus plotter. Put a sensitized board
on the plotter in a dark room. Replaced the pen with a focused
light source that turned on and off with the pen-up and pen-down
signal. I used to do Radio FAX pictures like this until I found
that metalized paper that burned when a current went through it.
