INKJET PRINTER

                       Inkjet Printer 



INKJET PRINTER EXPEL ink droplets from hundreds of tiny jets, or nozzles,  onto a medium, such a paper, to printer and image. each droplet corresponds to a single pixel ( Picture element).  Black-and-white  printers use only black ink, while colour printer over print combinations of a printing colours (cyan,magenta, yellow and black) to create a full colour range. the printhead containing the nozzle moves sideway across the paper, creating a line of pixel, before the paper moves slightly forward  show the next line  can be printed. Two basic methods are used to  eject ink : thermal,  in which ink is  heated to form an  expanding bubble that expels a droplet from the nozzle ,and piezoelectric, in which an electric current expands a crystal causing it to push out the ink droplet . The printer show here can print Digital Photographs directly from a memory card.
