Abstract
A host computer transmits raster information to a multi-color ink jet printer. The printer includes a printhead connected with an electrical processor. The printhead includes a plurality of arrays of ink jetting heaters. Each array of ink jetting heaters corresponds to a different color ink to be jetted onto the print medium, and is offset relative to an adjacent array of ink jetting heaters in an advance direction of the print medium. First raster information for a first raster is transmitted from the host computer to the electrical processor of the printer. The first raster information is associated with a first array of ink jetting heaters. The print medium is printed on by selectively actuating the ink jetting heaters of the first array of ink jetting heaters, using the first raster information. After the first printing step, second raster information for a second raster is transmitted to the electrical processor. The second raster information is associated with the first array of ink jetting heaters. After the first printing step, third raster information for the first raster is transmitted to the electrical processor. The third raster information is associated with a second a…
