A printer prints pictures, graphics, and texts on paper. It is connected to the computer and is used whenever we require a hard copy of any document present on our computer. We insert ink into the printer in the form of cartridges and the printhead sprays the ink on the paper, thus producing a printout.

Types of printers:

Printers are of two types:

  • Impact printers.

These types of printers make direct contact with the paper by pressing a ribbon against the paper where we want our printout. Few examples of impact printers are:

  1. Dot-matrix printers: Here, the graphics, texts, and documents are printed in the form of dots. The printhead of these printers contains 9 to 24 pins. With the increase in the number of pins, the number of dots increases and print becomes all the more clear. They can print 100 to 600 characters per second.
  2. Daisy-wheel printers: These printers are named so because they resemble a daisy flower with characters on each petal. A drum is used to strike on these petals which strikes against a coloured ribbon to give the respective print. They produce better quality printouts than dot-matrix printers but are no longer used. They can print 25 to 50 characters per second.
  3. Line printers: These printers can print one line at a time thereby increasing the speed of printing. These printers can print 1,200 to 6,000 characters per second.
  • Non-impact Printers: These printers do not make any direct contact with the paper. Few examples are:  
  1. Inkjet printers: Inkjet printers also print characters on paper in the form of dots. However, these dots are formed by spraying ink on the paper with the help of a nozzle.
  2. Laser printers: These are the most advanced form of printers. These days we find laser printers everywhere. They produce a high-quality image by producing a laser beam. They are also very fast.
