Output devices communicate processed data to users and include monitors, printers, speakers, and more. Popular printer types are inkjet and laser printers. Inkjet printers are inexpensive and use small jets of ink while laser printers are more versatile but costly, using toner, a drum, and fuser unit. Factors to consider for printers include speed, resolution, initial cost, and running costs. Other output devices include graph plotters, dot matrix printers, thermal printers, Braille printers, monitors, LCD projectors, and speakers.
