Correct Answer:
Option B —
Impact
The Principle: Impact PrintingA Daisy Wheel printer is a specific type of impact printer that was common in the 1970s and 80s. It works much like a mechanical typewriter.
Mechanism: It uses a circular plastic or metal wheel with "petals." Each petal has a raised letter, number, or symbol at the end.
The "Impact": To print a character, the wheel rotates to the correct position, and a tiny hammer strikes the back of the petal. This forces the character against an ink ribbon, which then presses against the paper to leave an impression.
Quality: Because it uses solid physical characters (like a typewriter), it produces very high-quality "letter-quality" text, but it cannot print graphics or different fonts without physically changing the wheel.
