Hello,
You will need to ensure both the iPad and printer are on the same network for AirPrint to work properly. Refresh your Wi-Fi connection. This will force the iPad to look for the printer again. To refresh Wi-Fi, open the iPad's settings, tap on Wi-Fi in the left-side list, and tap the green switch to turn Wi-Fi off.
Thank You.
