Dot Matrix
Dot Matrix printers are currently the most common
printers among all businesses. Dot Matrix printers
are inexpensive, impact printers that can provide draft,
near letter quality, and letter quality printing. The
image is formed by a head striking a carbon ribbon
onto a single or multipart form. Typically, the print
head has 9 or 24 pins which create the image. When
generating bar codes with a dot matrix printer, a low
resolution or density provides the best scanning results.
Some 24 pin dot matrix printers can generate acceptable
medium density bar codes.
