    I think we need to address the case of grayscale printing on a color
    device. I know of devices that always print in color unless grayscale data
    is sent. What if we added a DeviceFeature attribute on the ColorMode
    element to indicate if the driver needs to create the grayscale data or if
    the command sequence will cause the device to do the grayscaling?
