Abstract
A method of printing an image from a printhead module having a plurality of horizontal nozzle rows. Each nozzle row has a main row portion and a corresponding dropped row portion vertically offset from the main row portion. The method includes the steps of: determining a predetermined delay for the dropped row portions based on the offset, a print speed and a print resolution; allocating dot data for image lines to respective nozzle rows based on the print speed and print resolution, sending first dot data for each main row portion and second dot data for each dropped row portion to the printhead module; and firing nozzles from the main row portions and dropped row portion in a predetermined sequence. Each dropped row portion is fired independently of its corresponding main row portion and delayed relative to its corresponding main row portion by the predetermined delay.
