Editing Plotter (section)

===Electrostatic plotters===
[[Electrostatic plotter]]s used a [[xerography|dry toner transfer process]] similar to that in many [[photocopier]]s. They were faster than pen plotters and were available in large formats, suitable for reproducing engineering drawings. The quality of image was often not as good as contemporary pen plotters. Electrostatic plotters were made in both flat-bed and drum types. The electrostatic plotter uses the pixel as a drawing means, like a [[raster graphics]] display device. The plotter head consists of a large number of tiny styluses (as many as 21760) embedded in it. This head traverses over the width of the paper as it rolls past the head to make a drawing. The resolutions available may be 100 to 508 dots per inch. Electrostatic plotters are very fast with plotting speed of 6 to 32&nbsp;mm/s, depending on the plotter resolution.<ref name="R1"/>
