How does Auto-Off work on the HP Envy 6000 and when is it disabled?

Auto-Off turns the printer off completely after 2 hours of inactivity to reduce energy use, and you must use the Power button to turn the printer back on. Auto-Off is automatically disabled when the printer's wireless or Wi-Fi Direct capability is turned on, or when a printer with fax, USB, or Ethernet network capability establishes one of those connections. Even when Auto-Off is disabled, the printer enters Energy Save Mode after 5 minutes of inactivity.
