Problem:
PrintMe Connect stops working when I'm not logged into the PC running PrintMe Connect.

Symptom:
Printers aren't visible on the AirPrint enabled device.
You cannot ping the Wireless adapter IP of the PC running PrintMe Connect.

Solution or Workaround:
PrintMe Connect services will start automatically. However, some Wireless network adapters do not retain an IP address when you aren't logged into the PC. If you have a wireless adapter exhibiting this behavior you will most likely have to keep a user logged in for PrintMe Connect to remain active.
