What should I do if my printer 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, make sure the printer is connected to the same network as the device you are printing from. For Windows users, visit HP Diagnostic Tools at www.hp.com/go/tools to fix common printer problems.
