Abstract:
A method of transmitting data from a host computer to a multi-color ink jet printer, the ink jet printer used for printing an image on a print medium with a plurality of color inks, the print medium being movable in an advance direction, said method comprising the steps of:providing a host computer having an output, said host computer outputting raster information corresponding to a plurality of rasters of ink dot placement locations on the print medium in a direction transverse to the advance direction of the print medium;providing the ink jet printer with an electrical processor having an input which is coupled with said host computer output, said electrical processor receiving said raster information;providing the ink jet printer with a print head connected to said electrical processor, said printhead having a plurality of ink jetting heaters arranged in a plurality of arrays, each said array of ink jetting heaters corresponding to a different one of the plurality of color inks to be jetted onto the print medium, each said array of ink jetting heaters being offset relative to an adjacent said array of ink jetting heaters in the advance direction of the print medium;transmitting first raster information for a first raster from said host computer to said electrical processor of said printer, said first raster information for said first raster being associated with a first array of said plurality of arrays of ink jetting heaters;after said first transmitting step, transmitting second raster information for a second raster from said host computer to said electrical processor of said printer, said second raster information for said second raster being associated with said first array of ink jetting heaters; andafter said second transmitting step, transmitting third raster information for said first raster from said host computer to said electrical processor of said printer, said third raster information for said first raster being associated with a second array of said plurality of arrays of ink jetting heaters, said second array of ink jetting heaters being different from said first array of ink jetting heaters.
