Abstract
A method for printing grayscale images. A sliding window memory stores an array of exposure data. The memory is initialized (80) with zero values. The memory is then addressed (82) so that the last row of the array is filled with exposure data. A microimage is then generated based on the exposure data (84). The data in the array is then decremented (86). If the page to be printed is not completed, the array's addresses are rotated (82) so that the data for the first row drops out, the data for other rows is readdressed as the next row, and new data fills the last row.
