A. Ink-Jet
B. Dot matrix
C. Xerographic
D. Laser
Answer & Solution
Option: C
Explanation : Xerography also known as electrophotography is a printing and photocopying technique that works on the basis of electrostatic charges. The xerography process is the dominant method of reproducing images and printing computer data and is used in photocopiers, laser printer s and fax machines. The term derives from the Greek words xeros , meaning dry and graphos , meaning writing.
The original xerography process allowed for reproducing or printing only grayscale images. Later, the capability to reproduce and print color images was developed. High-end grayscale and color laser printers can provide hard copy nearly as good as that produced by an offset printer. Xerography may eventually supplant traditional printing for the production of books and magazines.
