Just a thought on the subject.. I may be very wrong.
As I recall, laser light is a VERY specific wavelength, not the usual
mix of assorted wavelengths that we perceive as white.
If the photosensitive material needs to be exposed by UV, I would
think that an off-the-shelf red laser pointer might never expose the
surface at all.

I like the idea though. It could offer great precision without
excessive wear on the printer parts.

If my beliefs regarding laser light are incorrect, I'm sure some
better educated person will point this out.
