FastRes 1200 FastRes 1200 (PCL 6 only) is an HP developed technology that can represent each dot space as one of four different levels of black. However, FastRes 1200 uses only 2 data bits to store information for the same dot space. This means that only half as much RAM is needed to print an image. FastRes 1200 takes advantage of HP’s new smaller toner particle (less than 5 microns) to provide superb test and image quality. C4085-91087 Image Formation System 107
