Hmm, electrostatically charge the laser-printer toner, and then
sprinkle it across the board?  

I suppose (if you were careful not to turn the board over or 
shake it too violently) you could mount it in a flatbed plotter
and trace out the places you wanted to etch with a Q-tip.  Then,
heat the board to fuse the toner, and you're ready to etch.

Naw, it probably wouldn't work.
