Abstract:
An arrangement for printing a raster image organized into a plurality of scan lines on a recording medium, the arrangement comprising:a memory containing scan line data representative of at least one of said scan lines; and a printbar comprising a plurality of nozzles and a printbar circuit, the printbar circuit including an output buffer and a serial data buffer; the serial data buffer including a serial data register corresponding to each nozzle, the serial data buffer operably connected to receive serially the scan line data such that the serial data buffer includes scan line data corresponding to a first scan line, the output buffer including an output register corresponding to each nozzle, the output buffer operably connected to receive the scan line data from the serial data buffer, the printbar circuit operable to cause the plurality of nozzles to print on the recording medium in accordance with the scan line data stored in the output buffer while the recording medium moves continuously in a process direction and wherein the printbar further comprises a first number of buffer registers interposed between the serial data register and the output register corresponding to a first nozzle, and a second number of buffer registers interposed between the serial data register and the output register corresponding to a second nozzle, the second number greater than the first number.
