A method that changes the image length and width produced by a laser printer to bring the printer's output into exact dimensional accuracy with the data input. This is accomplished by first a measuring sample page produced by the printer in response to a known input (52). Errors (figure 9), if any, are measured and fed back into the printer (figure 3) through a host computer (1), and the graphics controller uses this information to change the printed graphics in the vertical and horizontal dimensions. In one embodiment of the invention, the graphic depiction is scaled as it is converted from the display list to the dot image in the printer's RAM. In another embodiment, the resolution of the controller is changed to compensate for errors.
