To use library computers, you must have a library card - you can get one if you can prove you live in Arizona. You don't need a card if you use your own device to send document to printer. 20¢ per page to print black and white
It's $.20 for black and white actually.
About printing documents, yes, you do need to pay but it's $0.10 for every single page and $0.25 for each colored one. You also need a card for the computers there.
