Nowadays for quicker preparing and processing USB cables are used.Printers come in large variety of sizes and printers with particular task or for special purposes has been created and manufactured for speedier, precise and errand driven printing.
For instance, printing of pictures or photographs specific printers can be purchased from market.

The speed of printer can be described as the time taken to complete a single printout which varies from printer to printer. The speed of printers can be measured in CPS [Character Per Second], LPS [Lines Every Second], PPS [Pages every Second], The speed of obtaining printouts depends entirely on the quality of printer and the manufacturer.

Printers can be classified in two types ::

  • Impact Printers.
  • Non-Impact Printers.

IMPACT PRINTERS ::

Dot matrix and Daisy wheel printers are the prime examples of impact printers. Impact printer utilizes the component of standard typewriters. A hammer strikes the paper through the inked strip, the printer has a component which touches the paper with a specific end goal to make content or pictures. They deliver low nature and quality of printouts while printing they create noise as the hammer hits the paper through the inked strip.This movement makes irritating noise. They are tranquil less expensive and slow as compared with non-impact printers. The Speed of impact printer is measured in CPS [Character Per Second] and LPM [Line Per Minute]

DOT MATRIX PRINTER ::

Dot Matrix is an impact printer. This is the least expensive and low-quality printer which produces output in low quality. The dot matrix printer is broadly utilized and used as a part of substantial large associations where mass volumes of printing assignment must be finished.

Dot matrix printer is generally utilized as a part of printing receipts and bank statements because of its low-quality outputs. Many firms and organizations utilize and use Dot matrix printers for high volume of printout where quality is secondary.

Dotmatrix- printer output devices of computer system

This is the least expensive and famous impact printer. The printing rate of dot matrix printer is 30 to 140 CPS where CPS stands for character every second.

Dot Matrix printer utilizes predominantly two types of printing style.

  • Character based.
  • Line based.

They utilize a print head comprising of a progression of little sticks to hit a lace or ribbon with ink when this pins strike to the paper the ink is exchanged on the paper at the point of contact characters create are in set of dots or spots design or in matrix shape, the dot design relies on the pins exhibit in the head area.
