" Five example of Output Devices "

                                                                *Output Devices*


                  Impact printers
Refers to a class of printers that work by banging a head or needle against an ink ribbon to make a mark on the paper. This includes dot-matrix printers, daisy-wheel printers, and line printers. In contrast, laser and ink-jet printers are nonimpact printers. The distinction is important because impact printers tend to be considerably noisier than nonimpact printers but are useful for multipart forms such as invoices. 


 
                Non impact printer
A type of printer that does not operate by striking a head against a ribbon. Examples of nonimpact printers include laser and ink-jet printers. The term nonimpact is important primarily in that it distinguishes quiet printers from noisy (impact) printers. 



                      
                       Page Printer

page printer is a type of computer printer that prints on cut sheet paper. A modern page printer may use any of various technologies, such as laser, LED or inkjet. Most modern computer printers are page printers.







                   Plotter   
 A plotter is a computer printing device for printing vector graphics. In the past, plotters were widely used in applications such as computer-aided design, though they have generally been replaced with wide-format conventional printers, and it is now commonplace to refer to such wide-format printers as "plotters," even though they technically aren't.
