They do.  However, *accuracy* is as important as resolution, so if you
get a high-res printer that can't position an ink dot within 10 mil,
it's not going to be useful for PCB artwork.  Useful for photos,
because the key there is tight dithering so you don't notice the
individual pixels anyway.

If my laser jet were "perfect" I could do 1.3 mil traces.  It's not
the resolution that's the limiting factor, it's how accurately it can
place the toner/ink to realize those pixels.
