I don't know how you print on iOS, I assume the share sheet. But I'd think the easiest way would just be a WiFI/networked printer, and then however you get documents to it. I don't think you should need a special app. Apple support says you need an "air print enabled printer", whatever that is.
Unless things have changed over the years, this is just a printer that can receive printing requests, and batch queues, over the air. Just send something to air print, you can just use the share sheet, choose the print option, and follow the prompts.

Here's something a bit more generic, mentioning third-party apps, some by the printer manufacturers, some by others.

It sounds like air print is the easiest though, if you have a printer that can do it, you shouldn't need any extra apps. Good luck!
