Can nobody do anything about the crunchy mechanics of printers? My printer goes through the most incredible warmup routine, running the motors seemingly at random or about a minute and then twists the paper through a maze of rollers. Can we not make these things more 'solid state'?

Photolithography could work. The trick is to avoid waste and keep speed up, which are both really, really good properties of the drum/roller setup of a normal LED printer. So you'd probably have to use photosensitive paper rolling over a dense row of LEDs (kind of a reverse scanner). Which is basically what an LED printer is, except the paper is electrostatically charged and runs through a fuser to adhere the attracted toner.
