Function

An element of computer printer which printed characters on paper, by means of characters embossed on the ends of spokes of a wheel which were imprinted on paper by means of an inked ribbon. Printwheels/heads stamped characters on a sheet of paper when struck by a hammer. They came in different fonts [e.g. courier, prestige elite, bookface academic], font styles [e.g. bold, italic, regular] and in different sizes [e.g. 10, 12].

Technical

A good example of a printwheel produced for American Diablo/Xerox printers. The daisy-wheel printer was introduced in 1971 by Diablo Systems and shortly thereafter by Qume. In the daisy-wheel system, characters on the ends of petal like spokes radiating from a rotating flat disk were struck by a hammer and imprinted on the paper through an inked ribbon. The technology was used quite widely for operator console keyboards and word processing systems. Daisy wheel printers were prevalent in the 1970s. Consumers began to lose interest in these printers in the mid 1980s when newer technologies such as the dot-matrix, laser and inkjet printers appeared on the market. Another factor in the eclipse of the daisy wheel printer was the fact that the wheels/heads had to be removed manually every time a font needed to be changed, which was time consuming and tedious. Qume was co-founded by David Lee in 1973. He sold the company to ITTand then bought it back in 1988.
