the.com/dot matrix

Printing by a thousand tiny punches, loud enough to wake the office and your dad.

means A printing technology that forms letters and images from small patterns of dots, struck onto paper by tiny pins hitting an inked ribbon.

from Simply descriptive: 'dot' for the individual印 marks and 'matrix' in its old mathematical/typesetting sense of a grid or mold from which a pattern is formed — here, the grid of pins (often 9 or 24) that fire in patterns to build each character. The tech rose through the 1970s–80s as a cheap, rugged way to print, especially prized for multi-part carbonless forms, before quieter inkjet and laser printers pushed it into the niche of invoices and dot-matrix nostalgia.
