Which of the following printer can be classified as a page-at-a-time printer?
-

-
Dot-matrix-printer
-
Thermal Printer
-
Inkjet Printer
A
Correct answer
Explanation
Laser printers are page printers because they use a photoreceptor drum that receives an entire page's image as a single laser-scanned electrostatic charge pattern, then transfers toner to paper in one complete page pass. Dot matrix, thermal, and inkjet printers are all character/line-at-a-time printers that build images incrementally.
