Feeding a recording medium through a printer for printing images on the recording medium by actuating a line feeding motor in predetermined stepped increments, feeding the recording medium through the printer by a line feeding device driven by the line feeding motor, printing a image on the recording medium by a print head scanning across the recording medium and ejecting ink from nozzles, the print head having j nozzles spaced at a predetermined pixel resolution that is less than a pixel resolution printed by the printer, j being an integer number, controlling the actuating step to actuate the line feed motor in stepped increments, and controlling the j nozzles utilized in printing the image. For each stepped increment of the line feed motor, the line feeding device feeds the recording medium (mx1/n) pixels of the print head pixel resolution, where m and n are integer numbers and m is greater than n. The j nozzles that print in any one scan of the print head are controlled based on the number of increments of the line feed motor. Additionally, a print driver calculates a line skip amount and a buffer offset amount, and adjusts a starting position for storing of the image data in a print buffer in a case where a first line of image data to be stored in the print buffer is white data.
