What should I do if my HP Envy Photo 7100 won't print?

First, make sure you have installed the latest HP Smart app or printer software from 123.hp.com. If using a USB cable, ensure the cable is securely connected and the printer is set as the default printing device. If using a wireless connection, confirm the printer is connected to the same network as the device you are printing from. Windows users can also visit HP Diagnostic Tools at www.hp.com/go/tools to fix common printer problems. (Page 2)
