I would appreciate any help I can get on this subject. I have the new ipad3. I bought a hp wireless printer so I could print from my ipad....mostly photos. When I call up a photo and click the box/right arrow at the top right of the screen, it gives me the option to print but does not let me pick the size of the photo. I can print great 4 x 6 pictures but that's all it does. How do I print a 5x7 or 8x10??? I'm sure it can be done but I am on my last nerve trying to figure it out. Thank you in advance for your help!!!
