If you're looking for a way to make a non-AirPrint printer accessible to your iOS devices, I’ve developed a solution that could help. My script, AirPrint Bridge, is designed specifically for macOS users to enable AirPrint functionality for printers that don't natively support it.
You can find the full script and detailed instructions in the repository AirPrint Bridge on GitHub here -> https://github.com/sapireli/AirPrint_Bridge
