If I get an E-ticket for travel but don't have a printer to print it out?

For a surprise for my partners birthday I'd like to get tickets + travel to go to V festival, but I don't have a computer or a printer (I use my iPhone to go online) and it says you get your camping/festival tickets when you get there, and the coach tickets are sent as e tickets. But if I don't have access to a printer what do I do?

Most public libraries have computers you can use, as well as printers, that you can use. They charge a nominal fee for a print out (my library charges $0.20/page to print, for example.) Use of their computers is free, though you are required to sign up (for free) for a membership card.

Put the information on a flash/thumb drive and take it to Staples, Office Depot etc. And they will print it out or you
