First, ensure that your printer supports AirPrint - and that it has connected to the same WiFi network as your iPad. When correctly set-up, your iPad should automatically detect your Printer.


If set-up correctly, should you continue to experience difficulties, your WiFi Router may be unexpectedly failing to pass Apple Bonjour traffic on you local network - or your WiFi Router or Network Switch may be blocking this device discovery protocol.


The Apple Bonjour protocol uses mDNS (Multicast DNS) UDP port 5353.


You may find that restart of your network components will resolve the problem. You’ll need to restart your network devices in the correct order. Assuming that you WiFi Router provides DNS services for your network, restart devices in this order - allowing time for devices to fully boot/restart prior to restarting other devices:


  • WiFi Router
  • Upstream wired Network Switch(es)
  • WiFi Access Points / Network Extenders
  • Other fixed infrastructure devices - such as Printers
  • Client devices


Restarting your iPad, after restarting other devices in the correct sequence, is most simply achieved by a forced-restart of the iPad:


  • On an iPad with a Home button: Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.
  • On an iPad with Face ID: Press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the top button. When the Apple logo appears, release the button.




Be aware that the WiFi Private Address feature, found in iOS/iPadOS14 and later, can interfere with anticipated operation of other devices and services - such as AirPrint. In such circumstances, you may need to disable this feature - and can be enabled or disabled for each individual WiFi network that you use.


Use private Wi-Fi addresses in iOS 14, iPadOS 14, and watchOS 7 - Apple Support


Whilst this feature provides additional privacy and security when using “public” (untrusted) WiFi networks, this feature is largely unnecessary for your home WiFi network.
