1. A method for printing low-resolution digital image data received from a host computer on a digital printer, comprising:

  • receiving, on the digital printer, low-resolution image data transmitted from a host computer, wherein a data processor on the host computer formed the low-resolution image data by resizing full-resolution image data;

    receiving, on the digital printer, mask image data transmitted from the host computer, wherein a data processor on the host computer formed the mask image data by automatically analyzing the full-resolution image data or the low-resolution image data, the mask image data providing an indication of image regions in the low resolution image data that would benefit from the application of an anti-aliasing algorithm;

    using a data processor in the digital printer to resize the low-resolution image data, forming high-resolution image data at a higher resolution than the low-resolution image data;

    using the data processor in the digital printer to apply an anti-aliasing method to portions of the high-resolution image data corresponding to the indicated image regions in the mask image data, thereby providing anti-aliased image data; and

    printing the anti-aliased image data on the digital printer.
