    Inkjet Printer
                                                    This is a  non-impact  printer  that  outputs  text  and  images

                                                    by  spraying ink  on the  paper.  The speed  of this  printer  is
                                                    measured in lines per minute (lpm). These are comparatively
                                                    cheaper than laser printers and the quality of output is also a

                                                    little lower.

                     Dot Matrix Printer
                     This printer is an impact printer that contains a movable print head

                     with pins that strike the ribbon, placing a dot on the paper. These
                     printers are very noisy, less expensive and slow to work. The speed of

                     these printers is measured in characters per second (cps).

                                              Plotter

                                              Plotter is used for printing vector graphics, visual charts, tables and
                                              diagrams. Different types of plotters are:

                                                 Inkjet  Plotter: It sprays small droplets of ink onto  a piece of
                                                 paper, thereby creating an image.

                                                 Flatbed Plotter: The pen or the inkjet moves in horizontal and
                                                 vertical directions over a fixed horizontal flat surface on which the

                                                 paper is mounted.

                       Drum Plotter: It uses a drum revolver to move the paper and the pen or the jets of ink
                       during the printing process. The paper is placed over the drum which is then rotated.
                       The pen then moves along in a horizontal or vertical direction to print the output.

                                           A projector projects or displays data  from a computer screen onto a
                                           large screen or surface for the audience.
