ios14.2 airprint issues

Recently updated iPhones 7plus, iPhone se and iPad air3 to iOS 14.2 and find that none of these can now communicate to my printer via airprint. Message “ no AirPrint printers found” appears . All worked well prior to iOS upgrade

iPad Air 3, iPadOS 14

As described, your LAN infrastructure may not be passing 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
