===Drum===

Drum plotters reduced the required size of this technology, which using the same basic method.  Paper is attached to a large drum using a pin feed attachment.  The plotter then runs pens vertically across the paper, and the paper itself is moved horizontally by rotating the drum when needed.<ref name="techwalla.com">https://www.techwalla.com/articles/plotters-their-types</ref>

===Electrostatic===

===Electrostatic===

An electrostatic plotter charges portions of the paper negatively.  Older plotters did this by running a line of electrodes across the paper, although newer printers generally use laser, much like any other laser printer.  The toner is charged positively, so that is is attracted to the desired areas, where it is then fused.<ref>http://www.pcmag.com/encyclopedia/term/42512/electrostatic-plotter</ref><ref>http://link.springer.com/referenceworkentry/10.1007/1-4020-0613-6_6038</ref><ref>http://www.globalspec.com/learnmore/industrial_computers_boards/computer_peripherals/computer_printers_plotters</ref>

===Inkjet===

One of the newest and probably the most popular kinds of plotter uses the inkjet printing method.  Liquid ink is delivered to the paper as droplets using the inkjet method

===Cutting===

===Cutting===

A cutting plotter does not actually use ink to print forms, and by some definitions, may not even be considered a printer. These devices use a blade rather than a pen, and cut out pieces of material.  These pieces are usually used as graphics for signs and other media.<ref name="smallbusiness.chron.com">http://smallbusiness.chron.com/plotter-printer-work-33056.html</ref>
