Plotters are typically used in engineering to draw blueprints using CAD (computer aided design) and CAM (computer aided manufacturing). These printers were the first type of printer that could print color graphics. Plotter technology has advanced, and the once high-tech pen plotters have fallen into obscurity.
Another form of plotter is a cutting plotter, which uses knives to cut material used in graphics for advertising materials like the magnetic signs used on vehicles. As of 2014, laser cutters are starting to replace cutting plotters due to a higher level of versatility.Learn more about Printers
