The correct answer is: A. Laser printers
Laser printers use a combination of laser-beam and electro photographic techniques to produce high-quality text and images. The laser beam is used to create an image on a drum, which is then coated with toner. The toner is transferred to the paper and then fused to the paper using heat and pressure.
Dot-matrix printers use a series of pins to strike an ink ribbon, which then transfers the ink to the paper. Dot-matrix printers are typically used for printing text, as they are not as good at printing images as laser printers.
Line printers print one line of text at a time. They are typically used for printing large amounts of text, such as invoices or shipping labels.
Daisy wheel printers use a wheel with characters on it to print text. Daisy wheel printers are not as common as they used to be, but they are still used for some applications, such as printing checks.
None of the above options is correct.
