Pen-Based Plotters

A plotter is a vector graphics printing machine which operates by moving a pen over the surface of paper. Plotters have been (and still are) used in applications such as computer-aided design, though they are being replaced with wide-format conformist printers (which nowadays have sufficient resolution to render high-quality vector graphics using a rasterized print engine). It is general place to refer to such wide-format printers as "plotters", even though such handling is technically incorrect.
