For a swath of the image data, a start state of a random number generator is stored, and then a sufficient number of random numbers is generated such that each pixel has random number, or at least one bit of a random number, associated with it. The random number, or the portion of the random number, that is associated with a pixel determines during which pass that pixel is enabled for printing. To print a subsequent pass, the start state of the current swath is reset and the random numbers for the current swath are regenerated. To determine during which pass a pixel is enabled, the associated random number is combined with a different mask and/or complemented, or is compared to a different criterion, for each pass.
