Definition
Noun: A daisywheel printer is a type of impact printer that uses a rotating disk (the "daisy wheel") as its printing element. Each petal of this wheel has a raised character at its tip. To print, the wheel spins to position the desired character, and then a hammer strikes the petal against an inked ribbon, transferring the character onto the paper.
Usage
This term refers specifically to the complete printing device. It is a compound noun where "daisywheel" modifies "printer" to specify the printing mechanism. * The daisywheel printer was valued for producing high-quality, typewriter-like text but was very slow and noisy. * Before laser printers became affordable, many offices used a daisywheel printer for formal correspondence.
Advanced Usage
