Definition
Noun: A daisy print wheel is a component of a typewriter or printer. It is a circular wheel with flexible arms (resembling the petals of a daisy flower) radiating from a central hub. Each arm has a single character (a letter, number, or symbol) at its tip. The wheel rotates to position the desired character, which is then struck against an ink ribbon and the paper to create an impression.
Usage
