System and method for high quality bank check imprintation during high velocity passage of bank checks

A printer housing assembly provides dual in-line cartridges separated by a pre-set distance. Drive belts are used to pass documents such as checks at a high rate of speed past the nozzles of the dual cartridges. A delayed firing mechanism is provided between the two cartridges so that each cartridge will print exactly the same marking on the same spot of each document as it passes by. Further enhancements and contrast quality can also be developed by use of multiple cartridges more than just two cartridges which are placed in a specialized phased relationship to develop "dot-on-dot" printing of the same target by each individual cartridge.
