SOF Olympiad, please look into these wrong questions and solutions. Thank you.

Common examples of impact printers include dot matrix, daisy-wheel printers, and ball printers. Dot matrix printers work by striking a grid of pins against a ribbon. ... These printers, such as laser and inkjet printers are much quieter than impact printers and can print more detailed images
