What are the basic troubleshooting steps if my printer is not working?

First, make sure you have installed the latest HP Smart app or printer software from 123.hp.com. If using a USB cable, ensure it is securely connected and the printer is set as the default printer. If your computer is connected via wireless, make sure the printer is connected to the same network as your device. For Windows users, visit www.hp.com/go/tools to access HP Diagnostic Tools. (Page 2)
