Unit 2: Peripheral Different Types of Printer – A Device that prints text or illustrations on paper. There are many different types of printers. In terms of the technology utilized, printers fall into the following categories. 1. Dot Matrix A type of impact printer that produces character and illustrations. Dot Matrix printers vary in 3 important characteristics. Speed: the speed can vary from 50 to over 500 cps Print Quality: it can vary 9, 18 or 24 pins Ink: Dot Matrix Printer use ribbon for ink

Unit 2: Peripheral Ink-Jet: A type of printer that works by spraying ionized ink at a sheet of paper. Speed: the higher the PPM the more pages they can print. Most Ink-Jet Printers offer different speeds depending on the quality of print desired Print quality: Determined by the DPI Dot Per Inch, Example 2440 x 1220 DPI (Vertical and Horizontal DPI) The higher the DPI the better in terms of print quality. Ink: Ink-Jet printers use Ink Cartridgers (hidden cost)

Unit 2: Peripheral Laser: A type of printer that utilizes a laser beam to produce an image on a drum. The light of the laser alters the electrical charge on the drum wherever it hits. The drum is then rolled through a reservoir of toner, which is picked up by the charged portions of the drum. Finally the toner is transferred to the paper through a combination of heat and pressure.
