Abstract

A printer includes a printbar having plural dice partially overlap in the direction of rows and a halftoner. The dice receive nozzle firing data which determines when and where the individual print nozzles are to be operated in order to emit the colorant onto the media so as to form the desired printed image on a media. The halftoner is a bidirectional error diffusion halftoner that is structured to generate halftoned data. The halftoned data is mappable into the firing data. The halftoner includes a serpentine direction reverser which is structured to halftone print data image pixels in a first serpentine direction to form halftoned data and then to halftone print data image pixels in an opposite serpentine direction to form the halftoned data.
