A:Answer The short answer is yes. The information that printed during the setup process says "you can use this printer to print documents and photos on your mobile device (such as a smartphone or tablet). For more information, visit the HP Mobile Printing website (www.hp.com/go/mobileprinting)." It can automatically detect when one of three sizes of paper have been loaded. Currently, these sizes are letter (8 1/2 x 11 inches), 5 x 7 inches, and 4 x 6 inches. You can configure the printer to detect different sizes by using their app or going to the printer's home page.
