ABSTRACT:
A printer controller for an ink jet printer controls a print head to selectively print only a portion of the print dots at pixels locations in a print swath during each pass of a print carriage across a print medium. At least four passes are made before the print medium is advanced to a new print swath. The portion of the pixel locations for each pass are chosen such that no pixel location to be printed on that pass is orthogonally or diagonally adjacent to any other pixel location to be printed in the same pass. To improve linear print speed, the print carriage is moved across the print medium at a speed that is greater than a maximum firing rate for the print head divided by a print dot density for the ink jet printer.
