How drum plotter works?

A drum plotter operates by using a rotating drum to hold a roll of paper, which moves horizontally while a pen or ink cartridge moves vertically. As the drum rotates, the plotter's writing mechanism draws the desired image or text by controlling the pen's position and pressure on the paper. This allows for high precision in creating large-scale graphics and technical drawings. The combination of the drum's movement and the pen's action enables the plotter to produce detailed and accurate plots, often used in engineering and architectural applications.
