Abstract
A method and apparatus for processing image data are disclosed. The method includes the step of partitioning the image data into a plurality of data portions (μPage) for processing. Each data portion comprises a plurality of rows of pixels corresponding to at least one print swath height. The data portions are processed in a plurality of intermediate processing stages. The data portions are processed sequentially. The number of pixels per row of a data portion is determined to be just large enough ensure adequate output printing data for a given print head at all times. The processed data is then delivered to the print head in a just-in-time manner (JIT). An apparatus for processing the image data comprises an Application Specific Integrated Circuit (ASIC).
