In ancient prehistory-that is 20 or 30 years ago — most computer users didn’t have to distinguish a monitor from a printer. They worked at a “terminal” which consisted of a keyboard and a printing mechanism and which resembled an electric typewriter. The terminal printed all of the computer’s output, and the user’s input, on to continuous paper. As the teletype-like terminals were replaced by screens and printers, matrix technology developed on both classes of devices: on printers, needles made impressions on paper in a grid to form individual characters. On screen, rectangular cells of the sizes 8 x 8 or 8 x 16 dots served to represent letters. The bitmaps which represented the letters were built in to both classes of device, either in the printer’s memory or in the graphic card’s ROM.
