Abstract
A drum cartridge with a plurality of heads for use with an ink-jet printer. This inventive cartridge increases the speed of printing and the resolution of the printed matter. The drum cartridge moves in a rotational fashion rather than in the typical reciprocating rectilinear fashion used by typical ink-jet cartridges.
