An inkjet printer can print upto 2 to 10 pages per minute. Its printing is costly than that of dot matrix
                 printer but its quality is much better than that and it prints at a medium pace. Inkjet printer prints quality
                 images with resolution of 400 to 4000 dpi (dots per inch).

                      It is very fast as it operates in a similar mechanism as that of the
                      photocopy machines. The laser beam makes shadow of the images
                      with the help of a toner and transfers them on paper.

                      It is also known as Page Printer because it actually stores the content
                      of the page in memory before printing it. It can print up to 5–300
                      pages in a minute and the resolution output ranges from 600 dpi to
                      2400 dpi.

                 Plotter

                 Plotter is an output device that helps in printing high quality poster, flex, visuals, charts, graphs, tables and
                 diagrams, etc. It can draw continuous lines and can produce output on a paper, polyester film or coloured
                 transparencies. In plotter, the figures are drawn by an electronic pen which is driven by a motor. It uses
                 inkjet cartridges (single or multi-coloured) to spray colours for drawing and sketching.
                 Plotter is mostly used in CAD (Computer Aided Design), CAM (Computer Aided Manufacturing) and for
                 printing Banners and DTP Flexes. Plotter can be classified into four categories:

                 l    Flatbed Plotter                      l    Micro-graphic Plotter

                 l    Drum Plotter                         l    Inkjet Plotter








                                                      l       Flatbed Plotter: It consists of a fixed horizontal flat surface
                                                           on  which  paper  or  any  other  medium  is  fixed.  The  pen  is
                                                           mounted on a carriage that moves along the horizontal and
                                                           vertical axis to print over the medium.








                 l    Drum Plotter: It consists  of one or more pen(s)
                      which moves across the drum. The output medium
                      is placed  over  the drum.  The drum rotates either
                      clockwise or  anticlockwise under  the  control of
                      plotting instructions sent by the computer. The pen
                      is mounted on the carriage and moves along with
                      the carriage either ‘left to right’ or ‘right to left’ on
                      the paper to print.
