How to get epson WF-2540 to recognize my iPhone when the wifi originates with the phon

MMy old android had no problems being recognized by the printer even tho the wifi oroginated with the phone but my iPhone 6 cannot be identified by the printer while it also originates the wifi using an hotspot because I live in the country and cannot get DSL except from my phone is their a way I can AirPrint from my iPhone from this printer like I was able to do effortlessly from my Samsung Galaxy

thank you
