Same question on ITPEC: Oct 2024 Q23

Which of the following is an explanation of the printing method of an inkjet printer?

a)Printing is performed by directly spraying fine ink particles onto the paper.b)Printing is performed by using printing pins or other such component to hit an ink ribbon against the paper.c)Printing is performed by using the print head to heat ink that melts when it is heated.d)Printing is performed by using laser light to make toner adhere to a photosensitive body.

Explanation

Spraying fine ink particles onto the paper — the question asks how an inkjet printer puts ink on the page.

An inkjet printer's print head has many tiny nozzles that eject droplets of liquid ink directly onto the paper; nothing strikes the paper, so it is a non-impact printer. The droplets are pushed out by heating or by a piezoelectric element, but the defining feature is ink sprayed straight onto the paper.

Answer (a)

Why not others:

•(b) — pins striking an ink ribbon is a dot impact (dot matrix) printer
•(c) — heating ink that melts is a thermal transfer printer
•(d) — laser light and toner on a photosensitive drum is a laser printer

Key rule: Match each printer to how it transfers ink: inkjet sprays, dot impact strikes a ribbon, thermal transfer melts ink with heat, laser fixes toner from a photosensitive drum.
