Abstract
A scanning head ink jet printer utilizes variable paper advance interlacing. The printer includes a plurality of heads each having a plurality of rows of uniformly spaced ink jets which print different colors. A printing medium is advanced in a series of non-uniform distances (d.sub.1, d.sub.2, d.sub.3, d.sub.4) the sum of which is equal to the total number of uniformly-spaced ink jets (n) of one of the colors times the uniform spacing (s) of one pixel row from an adjacent pixel row. In a specific embodiment, a total advance of the printing medium is equal to the total number of uniformly-serial spaced ink jets of one color is 48, the spacing is four pixels, and the non-uniform distances include 49, 49, 45 and 49 pixels.
