Electrostatic plotter

Electrostatic plotter draws on negatively charged paper with positively charged tunner.As a rule plotters are much more expensive than printers.they are most frequently used for CAE (computer-Aided Engineering).A 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.

An Electrostatic Plotter produces a raster image by charging the paper with a high voltage. This voltage attracts toner which is then melted into the paper with heat.

This type of plotter is fast, but the quality is generally considered to be poor when compared to pen plotters.A plotter is a printer that interprets commands from a computer to make line drawings on paper with one or more automated pens. Unlike a regular printer , the plotter can draw continuous point-to-point lines directly from vector graphics files or commands. There are a number of different types of plotters: a drum plotter draws on paper wrapped around a drum which turns to produce one direction of the plot, while the pens move to provide the other direction; a flatbed plotter draws on paper placed on a flat surface; and an electrostatic plotter draws on negatively charged paper with positively charged toner.Plotters were the first type of printer that could print with color and render graphics and full-size engineering drawings. As a rule, plotters are much more expensive than printers. They are most frequently used for CAE (computer-aided engineering) applications, such as CAD (computer-aided design) and CAM (computer-aided manufacturing). Hewlett-Packard is the leading vendor of plotters worldwide.
