  3. 3. WHAT IS PRINTER?  A printer is an output device that produces text and graphics on paper.  Many printers are primarily used as local peripherals, and are attached by a printer cable or, in most newer printers, a USB cable to a computer which serves as a document source.  In addition, a few modern printers can directly interface to electronic media such as memory card, or to image capture devices such as digital camera.
  4. 4. TYPES OF PRINTER  Printers can be divided into two main groups, impact printer and non-impact printer.  Impact printer produces text and images when tiny wire pins on print head strike the ink ribbon by physically contacting the paper.  Non-impact printer produces text and graphics on paper without actually striking the paper.  Printers can also be categorized based on the print method or print technology.
  5. 5.  The most popular ones are inkjet printer, laser printer, dot-matrix printer and thermal printer.  Among these, only dot-matrix printer is impact printer and the others are non-impact printers.
  6. 6. DOT MATRIX PRINTER  The term dot matrix printer is specifically used for impact printers that use a matrix of small pins to create precise dots.  Each dot is produced by a tiny metal rod, also called a "wire" or "pin", which is driven forward by the power of a tiny electromagnet or solenoid, either directly or through small levers.  Such printers would have either 7 or 9 or 18 or 24 pins on the print head. 24-pin print heads were able to print at a higher quality.

  8. 8. INKJET PRINTERS  An inkjet printer is a type of computer printer that reproduces a digital image by propelling variably-sized droplets of liquid material (ink) onto a page.  Desktop inkjet printers, as used in offices or at home, tend to use aqueous inks based on a mixture of water, glycol and dyes or pigments.  A typical ink-jet printer provides a resolution of 300 dots per inch, although some newer models offer higher resolutions.

  10. 10. LASER PRINTER  Laser printers are non-impact printers which can print text and images in high speed and high quality resolution, ranging from 600 to 1200 dpi.  A laser beam projects an image of the page to be printed onto an electrically charged rotating drum coated with selenium.  Laser printers produce very high-quality print and are capable of printing an almost unlimited variety of fonts.

  12. 12. OTHER TYPE OF PRINTERS  Thermal printers The heat activates the thermo-sensitive coloring ayer of the thermo-sensitive paper, which manifests a pattern of color change in response  Photo printers Are color printers that produce photo lab quality pictures on photo paper.  All in one printers It is a machine that includes several functionalities including printer, scanner, copier and fax.
  13. 13.  Color printer Its new generation color printers which works on the principal of ink-jet printers.  Dye sublimation printer Which employs a printing process that uses heat to transfer dye onto a medium such as a plastic card, paper, or fabric
  14. 14. FUTURE  The main focus of all engineers is to develop “3D PRINTER” and “INKLESS PRINTER”.
