What do the different wireless light statuses mean on the HP OfficeJet 4650?

A solid blue light indicates that a wireless connection has been established and you can print. A slow blinking light means wireless is on but the printer is not connected to a network, while a fast blinking light indicates a wireless error — refer to the message on the printer display. If wireless is turned off entirely, the wireless light will be off and the display will show 'Wireless Off.' (Page 2)
