electrostatic plotterA plotter that uses an electrostatic method of printing. Liquid toner models use a positively charged toner that is attracted to paper which is negatively charged by passing by a line of electrodes (tiny wires or nibs). Models print in black and white or color, and some handle paper up to six feet wide. Newer electrostatic plotters are really large-format laser printers and focus light onto a charged drum using lasers or LEDs. See electrostatic.
|This early plotter from CalComp used a dry toner process like a laser printer. LEDs beamed light onto a charged plate and produced monochrome drawings at 400 dpi. (Image courtesy of CalComp, Inc.)|
