dot matrix printer
<hardware, printer> 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.
