Abstract:
A mixed-swath-height printer for forming images as an assemblage of ink dots at pixel locations on a printing medium; said printer comprising:means for holding the print medium;first printing means, for operating to print on the medium an image swath having a first swath height;second printing means, for concurrently operating to print on the medium an image swath having a second swath height that is greater than the first swath height;common supporting means for supporting the first and second printing means together, relative to the print-medium holding means;means for controlling the first printing means to apply ink to the medium by addressing the pixel locations at a first pixel density, wherein ""pixel density"" is defined as an actually-addressed fraction of a total number of addressable pixels; andmeans for concurrently controlling the second printing means to apply ink to the medium by addressing the pixel locations at a second pixel density that is different from the first pixel density.
