Returns or changes the Energy Star sleep value. If the value is greater than zero, then the device will go into energy saving sleep mode after the print engine has been idle for the number of seconds specified by this object. A value of zero means Energy Star is disabled and the device will not go to sleep based on print engine idle time. The value must be non-negative. Additional information: The HP LaserJet 2100 Series will always be in sleep mode when not processing data. This object will always return a value of 1.
