Which type of printer uses a drum, plastic toner, and fuser to create a printed page?

1. Inkjet Printers

2. Laser Printers

3. Thermal Printers

4. Plotters

The correct answer is: Laser Printers

Laser printers use a drum, plastic toner, and fuser to produce printed pages. The process begins when a laser beam generates an electrostatic image on a rotating drum, which attracts the toner particles to the charged areas. The toner is a fine powder that is fused onto the paper by passing it through a heated fuser unit, effectively melting the toner and adhering it to the paper. This technology allows laser printers to produce sharp text and images quickly and efficiently, making them ideal for high-volume printing tasks. Other printer types employ different mechanisms and materials. Inkjet printers utilize liquid ink sprays to create images, thermal printers rely on heat-sensitive paper, and plotters are specialized printers that create vector graphics for precise line drawings.
