Printer

  1. 1. COMPUTER ASSIGNMENT PRINTER
  2. 2. IMPACT PRINTERS <ul><li>In these types of printers, there is a physical contact between the print head and paper. </li></ul><ul><li>They can be broadly divided into:- </li></ul><ul><li>1.Line printers </li></ul><ul><li>2.Character printers </li></ul>
  3. 3. LINE PRINTERS <ul><li>Line printers print one line of text at a time. Their speed varies from 300 to 3000 lines per minute. Examples are Drum printers and Chain printers. </li></ul><ul><li>Drum printers : Consists of a cylindrical drum on which characters are embossed for each and every print position on a line. </li></ul><ul><li>Chain printers : Has characters engraved in type assembly on a chain . The chain is rotated at high speed where characters are printed. </li></ul>
  4. 4. CHARACTER PRINTERS <ul><li>Character printers print one character of text at a time. They are slow printers with a speed of 30 to 600 per second. It is mainly of 3 types: </li></ul><ul><li>Dot - Matrix : The printer head contains of vertical array of pins. As the head moves , selected pins fire against the ribbons . The more the pins it has a better quality. </li></ul><ul><li>Quality printers : These printers are like the Dot – Matrix but it forms lines not dotes. </li></ul><ul><li>Daisy wheel printers : The print head resembles the daisy flower . Its print arms are like the petals of the flower . The hub is continuously rotating and hammers at a appropriate time .Its speed is up to 90 units per second </li></ul>
  5. 5. NON – IMPACT PRINTERS <ul><li>Non impact printers use thermal, chemical, electrostatic, laser beam, or inkjet technology for printing. There is no physical contact between head and paper. They are faster than impact printers . </li></ul>
