ABSTRACT:
To print an image having a 600 dpi resolution along the horizontal axis with an ink jet printer that has a 300 dpi resolution, the method alternately examines the odd and even numbered pixel rows of the image. Odd-numbered rows are examined in a left-to-right manner while even-numbered rows are examined in a right-to-left manner. In odd-numbered rows the even numbered pixels are deleted. In the even-numbered rows, the even numbered pixels are deleted starting from the right-most pixel. After deleting the respective pixels, ink drops are fired from the ink jet printer at areas corresponding to the remaining ON pixels. This visibly reproduces the image at the 600 dpi resolution.
