Abstract:
System(s) and method(s) for text enhancement in printing material saving mode are described. In an example, a method comprises identifying a type of a pixel based on edge tag data associated with the pixel, where the edge tag data is indicative of whether the pixel is an edge pixel or a non-edge pixel. The method further comprises determining at least one material saving parameter based on the type of the pixel. Further, the method comprises modifying a quantization error value based on the at least one material saving parameter. The method further comprises distributing the modified quantization error to a set of unprocessed pixels.
