Abstract
A full width array raster imaging interface for an ink jet printer. The raster imaging interface transforms raster information for printing by a thermal ink jet full width array printbar. The transformation includes dividing scan lines of the raster information into segments corresponding to the number of die in a printbar and to delay the printing of each subsequent segment by one scan line. The transformation is necessary since the printbar prints a single line of pixels in a burst of several banks or segments having a plurality of nozzles. The banks of nozzles are fired sequentially and the nozzles within a bank are fired simultaneously.
