Hello,
I am currently facing an issue with AirPrint in an enterprise environment with a large deployment of network printers, and the behavior is quite inconsistent.
Symptoms:
Inconsistent printer discovery: When attempting to use AirPrint, the list of available printers changes constantly. The available printers differ depending on the specific iPhone being used and it differ each time.
Intermittent print failures: Even when a printer does appear and is selected, printing occasionally fails.
Device discrepancy: We tested using an iPhone 16 and an iPhone 14 running the exact same iOS version, yet we obtained completely different results each time. The iPhone 16 in particular encounters significantly more errors when trying to print.
Environment & Troubleshooting so far:
The Bonjour protocol has been properly configured across our wireless Access Points (APs).
Firewall rules are correctly set up, and we have verified that the traffic flows are passing through as expected.
Has anyone experienced similar behavior with AirPrint inconsistency across different iOS device models, or are there specific multicast/Bonjour settings we should review for newer iOS versions?
Any insights or recommendations would be greatly appreciated. Thank you!
