Of all the printer types, this is the oldest type. Inspired from typewriter, this printer operates by having its pin strike against the ink ribbon. The print out from dot matrix is easily recognized because of the obvious lines and dots that you can see on the image or character it prints; hence it is called dot-matrix. Despite its obsolescence, dot-matrix printer is still used by some business establishments because its mechanical pressure enables the producing of carbon and carbon-less copies.
