Quito airport check-in

I purchased a plane ticket online (Quito to the US) via my smartphone. I don't have a computer.  

Do I need to print a hard copy of the flight itinerary at an internet cabina for presentation to airport personnel -- to be allowed to enter the airport, or for any other purpose?

Thank you,
