Abstract
The text to be classified as a dot matrix or ink jet printer character is scanned at a suitable resolution. Several horizontal and vertical slices are made through the bitmap image of individual characters. Density values of pixels contained in these slices are stored as a density profile for each slice. As a result of these density profiles, a determination is made as to whether or not the character was printed on a dot matrix or ink jet printer, or whether the characters were printed using a higher quality device such as a daisy wheel printer.
