10.  Plotters are used for plotting graphs and
designs on paper.
 Architects and designers use plotters to
produce blueprints of their designs on paper.
 It is a specialised output device for preparing
computer drawn charts and graphs.
 The most popular type of plotter is the flat
bed device. It plots on paper (or other
material) that is spread on a flat bed.
