Printers as an Output Device of Computer and Their Types

Printers are the prime example of OUTPUT DEVICE of the computer system. They are peripheral devices or electronic gadgets that produce output or outcomes on paper. which are called HARDCOPY.

Printers are associated with modern-day computers or PCs by means of USB or LPT Port with printer cables.

Nowadays for quicker preparation and processing USB cables are used.

Printers come in a large variety of sizes and printers with a particular task or for special purposes that have been created and manufactured for speedier, precise, and errand driven printing. For instance, the printing of pictures or photographs specific printers can be purchased from the market.

The speed of the 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 the printer and the manufacturer.

Printers can be classified in two types

  • Impact Printers.
  • Non-Impact Printers.


Dot matrix and Daisy wheel printers are prime examples of impact printers. The impact printer utilizes the component of standard typewriters.

A hammer strikes the paper through the inked strip, the printer has a component that 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 an irritating noise.

They are tranquil less expensive and slow as compared with non-impact printers.

The Speed of the impact printer is measured in CPS [Character Per Second] and LPM [Line Per Minute].


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 assignments 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 a high volume of printouts where quality is secondary.

This is the least expensive and famous impact printer. The printing rate of the dot matrix printer is 30 to 140 CPS where CPS stands for a 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 these pins strike the paper the ink is exchanged on the paper at the point of contact characters create are in the set of dots or spots design or in a matrix shape, the dot design relies on the pins exhibit in the head area.

Dot-matrix printers can have 5,7,9,18,24 sticks on the head area, whereas a 24 stick printer would give high calibre or high-quality Output.


Laser and inkjet printers are prime examples of non-impact printers. These printers use laser and electrostatic innovation and technology for printing.

They don’t deliver any clamour or noise as they don’t touch the paper while creating outputs. They utilize chemicals, warmth, and electric signs for making content and pictures.

They are more costly when compared with impact printers, their quality is better, while printing they don’t touch the paper consequently they are quiet and their speed is faster than impact printers.

The speed of the non-impact printer is measured in PPM Pages Per Minute.


A Laser printer is a type of non-impact printer. They create great outputs when contrasted or compared with Dot-matrix printers, they are costly, faster compared to dot-matrix printers.

Their speed is measured in PPM (Pages Per minute) it can print from 10 pages to 300 pages for every moment. They print page by page.
