Currently, I can search my printer with Bonjour/SNMP
protocol by
NSNetServiceBrowser
NSNetService
Now I want to print my document by IPP protocol.
Could you please tell me way to print with IPP in iOS?
Usually iOS Apps don't care about the printer protocol. It's sufficient to use Apples AirPrint focused Print-API. I can't see how UIPrinter would expose details like IPP connections through the API.
If you don't want to use Apples API for printing, you should implement IPP. A good start could be to look at my simple print-job implementation written in java. I'd be happy to assist in porting this to Swift of Objectiv C.
