Abstract

Data input received by a printer is printed. Dot data, which indicates location of dots on a print medium, is generated from the data input. Dot shift data is used in order to make sub-pixel shifts in locations of a subset of the dots on the print medium. Pulses are provided to a printhead which result in ink being emitted through nozzles located on the printhead. When placing the dots on the print medium, sub-pixel shifts in locations of the subset of the dots is achieved by time shifting the occurrence of pulses used to generate the dots.
