Why has my printer stopped working with my iPad?
Check that the printer has its wireless connection switched on. Ensure your iOS device is not in AirPlane mode. Ensure all devices are on the same network. Check that both the iPhone/iPad and printer are running the latest software.
Why is AirPrint not working?
If an AirPrint-enabled printer isn’t showing up on your iPhone, head to the printer’s network settings and ensure its Wi-Fi is enabled. Most importantly, make sure the printer is connected to the same Wi-Fi network as your iPhone. If the problem persists, the printer could be blocked or blacklisted on the network.
