Abstract
A method of printing an image from a printhead module having a plurality of horizontal ink planes M supplied with a same ink. Each ink plane has a nozzle row and the nozzles rows of all ink planes have vertically aligned nozzles. The method includes the steps of: defining contiguous span groups along each nozzle row, each span group containing N nozzles; allocating dot data for each image line of the image to a predetermined number of nozzles P in each span group of each nozzle row; sending the dot data to the printhead module and firing nozzles sequentially from the ink planes to print the image line. Only one nozzle from each span group in a same nozzle row is fired simultaneously, N is an integer multiple of M, and P is N divided by M.
