A laser jet printer uses a laser to deliver the necessary energy to the ink-containing ribbon in order to deliver ink therefrom to the recording medium, such as paper in the form of microdrops. There are two basic concepts to accomplish laser jet printing. The first is with a single pulsed laser which is deflected by a refractor, and the second is with an array of pulsed lasers which cover the desired print-swath height on a laser per pixel basis. No refractor is necessary, of course, for the array of lasers in the second concept.
