daisy wheel - Computer Definition
An earlier print mechanism that used a plastic or metal hub with spokes like an old-fashioned wagon wheel minus the outer rim. At the end of each spoke is the carved image of a type character. When the required character spins around to the print hammer, the image is banged into a ribbon and onto paper. The mechanism is then moved to the next location. Daisy wheel printers print typewriter-like quality from 10 to 75 cps and have been superseded by dot matrix and laser printers.
