-Laser Printer (non impact): suitable for high volume printing. Prints in b&w or colour.
-Ink jet Printer (non impact): suitable for home use. High quality print. Prints in b&w or colour.
-Plotter (impact printer): can use large paper sizes. Drawings are high quality, can draw arcs and curves and different characters and fonts. Used by architects, surveyors, pattern makers and engineers.

They are an alternative to a mouse. They are also known as a touch sensitive pad. One other advantage is that they can sense the touch of a finger. One major disadvantage is that it can sometimes be very sensitive and becomes very difficult to use.
