Dot matrix printers use a pattern of tiny ink dots to print images in a lower quality than other printer types but are less expensive. Laser printers use a laser beam and toner cartridge to print higher quality images. Inkjet printers use an ink cartridge and printing element to produce an even finer printed image. A hard disk drive is a non-volatile storage device that stores data on rapidly rotating magnetic platters and is faster than an external disk drive.
