non-impact printer
     
         Any printer, such as a {laser printer}, {ink-jet
        printer}, {LED page printer}, that prints without striking the
        paper, unlike a {dot matrix printer} which hits the paper with
        small pins.  Non-impact printers are quieter than impact
        printers, and also faster due the lack of moving parts in the
        print head.
