What do the different wireless light indicators mean on my HP Envy Photo 6200?

A solid blue light indicates that wireless connection has been established and you can print. A slow blinking light indicates that wireless is on, but the printer is not connected to a network and you should make sure your printer is within range of the wireless signal. A fast blinking light indicates a wireless error and you should refer to the message on the printer display. No light indicates that wireless is off.
