Patent ID: 6942317

Claim:
A method for controlling a fluid ejecting apparatus having a reciprocable fluid ejection head to print swaths in as swath direction of at least one fluid on a receiving medium based on received ejection data, the fluid ejection head having a plurality of sections of nozzles that extend parallel to a process direction of the receiving medium and that eject different fluids, a first one of the sections of nozzles ejecting a first one of the different fluids and having a width in the process direction that is at least N times wider than the width in the process direction of each one of the other sections, where N is a number greater than one, the method comprising: receiving the ejection data from a data source; collecting data corresponding to the first one of the different fluids from the data in a data buffer until the data buffer is full; controlling the fluid ejection head to eject the first fluid only when the data buffer is full, such that the fluid ejection head ejects fluid from the first section of nozzles only in one out of every N swaths an the portion of that one of every N swaths receiving the first fluid will be N times wider than the width of each one of the other portions of that swath that receive fluids other than the first fluid.
