My printer is air print enabled, but my iPad will not recognize the printer.

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

Try to disconnect all devices from your wifi modem-router. Restart the modem-router and wait for it's complete autoconfiguration, then reconnect your printer and your iPad.
