Why does the HP Smart software fail to find my printer when setting up from a mobile device?

If setting up with a mobile device, Bluetooth and location services must be turned on so the software can find your network and printer. HP notes that your location is not being determined and no location information is sent to HP as part of the setup process. You should also ensure your mobile device is close enough to the printer to be within range of its Wi-Fi signal. (Page 3)
