Dot matrix printers were widely used during the 1970s and 1980s. Unlike today’s inkjet printers, dot matrix printers had nine or 24 pins on the print head. Early versions were designed with only seven pins and did not print descenders. Early home computer printers used a striking mechanism called the Seikosha Uni-Hammer, which used a solenoid to actuate a striker seven times for every seven-pixel column.
