Device Icon File
A device metadata package can contain one photo-realistic image, or icon, that represents the device in the Devices and Printers user interface. The image is stored in an icon file, and the file name must be specified in the DeviceIconFile element of the package's DeviceInfo XML document.
If the device metadata package does not contain a device icon file and DeviceIconFile element, the Devices and Printers user interface displays a default icon for the device. This icon is based on the device's category type that is specified in the DeviceCategory element of the DeviceInfo XML document.
