When set the object will cause the transfer setting of the device to be changed to the nearest appropriate value. When the object is read it will return the current transfer setting. Each engine will have different supported values. The object should snap to the nearest supported value. Different products could use this value in different ways. Typically, this value would be a voltage on an EP system, but could be a pressure level on an inkjet. Additional information: This setting is a voltage adjustment in the LaserJet 2200. Any value >= 150 snaps to 200.
