What basic troubleshooting steps should I take if my printer isn't working?

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 using wireless, make sure the printer is connected to the same network as your device. Windows users can visit www.hp.com/go/tools to use HP Diagnostic Tools. (Page 3)
