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.
TYPE 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.
 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.
Presentation printer
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.

INKJET PRINTER
   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.

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.

OTHER TYPE OF PRINTER
   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.
   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
