are binary.

as opposed to simply turning the pixel on or off.
Resolution
The spacing of pixels the printer can address and resolve individu-
ally, usually measured in the number of dots per inch (dpi).
Text
Alphabetic and numeric characters and symbols.
Graphics
Any of a variety of pictorial representations, including basic line
art, charts, and graphs, usually electronically generated from a
software application.
Images
Visual data typically scanned from original sources external to the
PC, such as photographs or video frames.
Gray Scales
Graphics or images consisting of gray dots representing a range of
intensities, as opposed to black only dots; gray scale objects must

printer.
