Question 2 • Computer Science Foundations

use a laser beam and static electricity to transfer words and images to paper.

Answer
A
Inkjet printers
B
Laser printers

Explanation

Laser printers use a laser beam and static electricity to form text and images on a page. The charged toner is attracted to the areas marked by the laser and then transferred onto the paper, so “Laser printers” is correct. Inkjet printers instead create images by spraying tiny droplets of liquid ink.
