X-Y plotter
From Wikipedia, the free encyclopedia
A X-Y plotter is a plotter that operates in two axes of motion ("X" and "Y") in order to draw continuous vector graphics. Plotters differ from Inkjet and Laser printers in that a plotter draws a continuous line, much like a pen on paper, while inkjet and laser printers use a very fine matrix of dots to form images, such that while a line may appear continuous to the naked eye, it in fact is a discrete set of points.
Technically speaking, all plotters function in two axes, such that referring to a plotter as an "X-Y plotter" is a bit redundant.
See Plotter for a more detailed explanation of the function of a plotter.
