A plotter is an output device that prints vector graphics on hard copy. Unlike printers, which are designed for raster graphics and text, plotters are specialized devices used to produce high-quality drawings, diagrams, and other vector-based illustrations. Plotters use pens or other drawing tools to create precise lines and shapes on paper, making them particularly useful for applications that require detailed and accurate graphical output, such as architectural and engineering designs.
