1.3.6.1.4.1.11.2.3.9.4.2.1.1.1.2
Returns eTrue if the device is in energy saving sleep mode, otherwise returns eFalse. Setting SLEEP-MODE to eFalse causes the device to wake up, if it is in sleep mode. Setting SLEEP-MODE to eTrue causes the device to go into sleep mode. Additional information: This object returns eTrue if the device is in energy saving sleep mode, otherwise it returns eFalse. Setting this object to eTrue while the printer is awake will not change the printer's current state and will return status. NOTE: This object should behave this way when the printer does not have an instant-on fuser. Setting this object to eTrue while printer is already in Sleep Mode will not change the printer's current state and will return status. Setting this object to eFalse while printer is already awake will not change the printer's current state and will return status. Setting this object to eFalse while the printer is asleep causes the device to wake up.
