I can print front laptop but no air printer found on iPhone

[Relentless66]

the printer prints fine wirelessly from our laptop. But with our iPhones it says no air printers found. If we turn off printer and turn it on, our iPhones then can find the printer and we can print. But 10 minutes later if we try and print again, our iPhones say no printer found.

I understand your concerns and I would like to help. We need to check few details first and we could try adding the printer as Airprint

- Do you have any Anti-virus software installed on your iPhone? If you do, please deactivate it for now.

- Ensure the printer and the iPhone are connected to the same wireless network.
-Note:- This printer supports only 2.4GHz network. Do not connect it to 5 GHz Network incase your Router supports both 2.4 and 5 GHz
- If you have a Dual-band router and both 2.4GHz and 5GHz networks share the same name/SSID, then the printer will not be able to connect to the network. In this case, contact your Internet service provider to assign different names to both the networks.

Please check with your Internet service provider if your router is able to forward 'Bonjour packets'. This is very important

Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network using multicast Domain Name System (mDNS) service records. The software comes built-in with Apple's macOS and iOS operating systems.

Next ensure your iPhone and Printer have the latest updates
