Abstract
A method and apparatus for printing rasterized images while economizing printing resources, on the basis of input image data corresponding to a predetermined original format, are provided. The method includes reducing the input image relative to the original format; on the basis of the reduced-scale image, forming a raster of image points each defining either a point to be printed or a blank point of the rasterized image; enlarging the raster of points to return to the original format by inserting blank image points in the reduced raster by a predetermined filling procedure; and printing the image on the basis of the point raster enlarged to the original format.
