Q1. Which of the following printers is noiseless, high-speed, and of high quality?
Explanation
A laser printer uses a laser beam, toner, and an electrostatic process to produce sharp, fast, and generally quiet output, so it fits all three clues in the question. A typewriter is noisy, slow by modern printing standards, and not a computer printer. A dot-matrix printer strikes pins against an inked ribbon, so it is noisy and gives lower print quality. An inkjet printer can print good-quality output and is fairly quiet, but it is usually slower than a laser printer and is not the best match for high-speed office printing.
