Print dot placement in an ink jet printer

Data input (21) received by a printer (11,12,13,14) is printed and dot data (24), which indicates location of dots (71-78) on a print medium, is generated from the data input (21). Dot shift data (22) is used in order to make sub-pixel shifts in locations of a subset (72-75,77) of the dots (71-78) o...

Zusammenfassung:	Data input (21) received by a printer (11,12,13,14) is printed and dot data (24), which indicates location of dots (71-78) on a print medium, is generated from the data input (21). Dot shift data (22) is used in order to make sub-pixel shifts in locations of a subset (72-75,77) of the dots (71-78) on the print medium. Pulses are provided to a printhead (13) which result in ink being emitted through nozzles located on the printhead (13). When placing the dots (71-78) on the print medium, sub-pixel shifts in locations of the subset (72-75,77) of the dots (71-78) is achieved by time shifting the occurrence of pulses used to generate the dots (71-78).
