         a kind of printer with a vertical column
        of up to 48 small closely packed needles or "pins" each of
        which can be individually forced forward to press an ink
        ribbon against the paper.  the print head is repeatedly
        scanned across the page and different combinations of needles
        activated at each point.
     
        dot matrix printers are noisy compared to non-impact
        printers.
