Which of the following is a non-impact printer?

Daisy wheel printer
Drum printer
Laser printer
All of the above E. None of the above

The correct answer is: E. None of the above

A daisy wheel printer is an impact printer, while a drum printer and a laser printer are non-impact printers.

An impact printer works by striking an inked ribbon against paper to create an image. A daisy wheel printer is a type of impact printer that uses a wheel with raised characters to print text. The wheel rotates until the desired character is in position, and then a hammer strikes the ribbon against the paper, transferring the ink to the paper.

A drum printer is a type of non-impact printer that uses a rotating drum to print text. The drum is coated with a thin layer of ink, and an electric charge is applied to the drum. The charge attracts ink to the areas of the drum that are not charged. The drum then rotates past a piece of paper, and the ink is transferred to the paper.

A laser printer is a type of non-impact printer that uses a laser to print text. The laser is used to create an image on a drum, which is then used to transfer the image to paper.

Impact printers are generally slower than non-impact printers, and they can be noisy. However, they are more reliable than non-impact printers, and they can print on a wider variety of paper types. Non-impact printers are generally faster and quieter than impact printers, and they produce higher quality prints. However, they are more expensive than impact printers, and they can be more difficult to maintain.
