<p>A page-wide array inkjet printer allocates the processing tasks for individu al printheads within the array to separate halftoning processors. Each halftoni ng processor processes the information relating to a strip of the image, with t he boundaries between strips running parallel to the print medium advance direction. In a preferred embodiment, the pixels within each strip are processed using a forward error diffusion algorithm operating along columns of pixels parallel to the strip boundaries. The resulting halftone data is supplied from each halftoning processor to one or more uniquely associated printing component controllers, and these controllers generate print instructions for printing components (e.g. inkjet printheads) connected to t he printing component controllers via a dedicated communications channel.</SDOA B></p> |
