Image output apparatus comprising a marking engine (3); and a marking engine control system (2) for supplying data defining an image in a suitable format to the marking engine to cause the marking engine to output the image. The marking engine control system includes a system for: 1) determining from the data defining the image, or from the condition of the marking engine control system, whether the marking engine could output an image of a predetermined type which is not to be output, and if it could not, controlling the marking engine to output the image; and 2) if it is determined in step 1) that the marking engine could output an image of the predetermined type, determining from the data defining the image whether the image includes image characteristics indicating that the image is of the predetermined type; and controlling the marking engine to output the image only if the image is determined no to be of the predetermined type. |
