Abstract: A method of printing a high resolution image with a printhead in a multi-pass printing mode includes subdividing the high resolution image into a plurality of low resolution sub-images; subdividing each low resolution sub-image into a plurality of low resolution swath portions; and allocating an amount of a memory for buffer storage, the amount being only sufficient to store data corresponding to less than two of the low resolution swath portions. The method also includes, for each low resolution swath portion: halftoning each low resolution swath portion to generate a corresponding halftoned low resolution swath portion, the halftoning of each low resolution swath portion of a particular low resolution sub-image being performed independently of halftoning the low resolution swath portions of other low resolution sub-images; storing the halftoned low resolution swath portion into the amount of the memory; and printing the halftoned low resolution swath portion.

Abstract: A print medium is printed on with a printhead of an ink jet printer. The print medium is advanced in an advance direction a predetermined amount. The print medium is printed on with the printhead in an area corresponding to the predetermined amount. A determination is made of an end of printable area on the print medium in the advance direction. The print medium is advanced in the advance direction a minimum reliable move amount, dependent upon the end of printable area determination. The minimum reliable move amount is less than the predetermined amount. The print medium is printed on with the printhead in an area corresponding to the minimum reliable move amount.
