Explain the types of printers

 Printers can be classified on a number of parameters like: mechanism used for printing, the speed of printing, the quality of output and the direction of printing. There are 2 types of printers: 1) Impact Printer-  Feature- Characters are printed by pressing a typeface against an inked ribbon so that it makes a mark on the paper. Example- Dot-matrix is a type of impact printer. These printers are not commonly used these days. 2) Non-impact Printer-  Feature- There is no contact between the typeface and paper while printing. They don't create noise while printing because their printing heads do not strike the paper. Example- 1. Laser Printer- It uses a beam of light to form images and print characters on the paper using toner ink as a medium. 2. Inkjet Printer- It uses jets of ink to print characters on paper. It consists of cartridges of 3 colours- magenta, yellow and cyan inks to create colour tones. These printers are commonly used these days.
