Abstract
Sub-pixel alignment is performed for dots from multiple printheads. In order to align, output from a first printhead is aligned with output from a second printhead, dot data is generated for the first printhead and for the second printhead. The dot data is generated from data input. The dot data indicates location of dots on a print medium. Dot shift data is used in order to make sub-pixel shifts in locations of first dots placed on the print medium by the first printhead in order to align the first dots placed on the print medium by the first printhead with second dots placed on the print medium by the second printhead. The first dots and the second dots are then placed on the print medium.
