A plotter takes a drawing that the computer has already prepared and puts it on paper with a moving pen, so data travels out of the machine and never into it.

It builds the image of a whole page on a photosensitive drum with a laser beam, then picks up dry toner on that image and fuses it onto the paper with heat and pressure.

A plotter holds a pen against the paper and moves it, so it draws continuous lines rather than building the image out of dots.

A plain scan is only a picture of the page, and nothing in it can be searched or corrected. OCR examines the shape of every character in that picture, matches it against the letters it knows and hands back real text that can be edited in a word processor.
