Explanation:

- Impact Printer: Uses physical contact to transfer ink to paper. They are typically used for tasks like printing multipart forms. Quality can be lower than other printers.

- Non-impact Printer: Uses methods like laser or inkjet to print, avoiding direct contact. They produce high-quality prints with sharp text and images.

- Plotter: Specializes in large-scale drawings and graphics. They offer precision, but not necessarily suited for typical document printing.

- Scanner: Captures digital images of physical documents. It doesn’t generate print output but digitizes information.
