Can you use your iphone5 to print photos off at boots?

I have the USB cable off my charger and my phone but I do t know if you can just like plug it into the machine like that or?

Depends on your printer. If your printer can read whatever is in your phone, then yes. You need to tell us more. Or just use AirPrint. Most printer nowadays have them. It allows you to print from your iPhone wirelessly without setting anything up.

P.S. I don't think this is in the right category. Post it in Computers next time.

Yeyou can all you need is the cable plug in the cable to your phone and the usb in the usb slot at the boots printer and follow the steps it will show on the screen, i have done it before.
