The present invention is embodied in a system and method for producing print masks to eliminate step advance and swath height error banding. In general, a print mask is probabilistically produced that corrects swath height errors and step advance errors. A printhead controller determines the firing order of the nozzles in a single or multiple swath with particular reference to a probabilistic print mask generator. The generator functions to firstly calculate the ramp height on a formula to include pen height, data resolution, the number of passes and the pen nozzle resolution. Secondly, taking the ramp height into consideration, the controller allocates on a random basis from the print mask, the firing of nozzles, so that the ramp may begin at zero, although other values may be desirable in preserving the life of the printhead, and ends at the ramp height.
