Q. one of the following printers is suitable for printing sprocket fed carbon copies?

A
Laser
B
Dot matrix
C
Ink jet
D
Drum
Solution:

Dot matrix (impact) printing is a type of computer printing which uses a print head that moves back-and-forth, or in an up-and-down motion, on the page and prints by impact, striking an ink-soaked cloth ribbon against the paper, much like the print mechanism on a typewriter. However, unlike a typewriter or daisy wheel printer, letters are drawn out of a dot matrix, and thus, varied fonts and arbitrary graphics can be produced.
