10. Types of Printers cont.
Laser Printer – A laser printer is a high-speed printer that is ideal for business documents and graphics. Laser printers produce the highest quality images, but are relatively expensive.
A laser printer works like a photocopier to produce images on a page. A laser beam draws images on a light-sensitive drum. The drum picks up a fine powdered ink called toner, and then transfers the toner to the paper to create the images.
Laser printers produce higher-quality print than ink jet printers, but are more expensive.
