Why is my HP wireless printer offline?
Check to make sure the printer is turned on and connected to the same Wi-Fi network as your PC. Your printer’s built-in menu should show which network it’s connected to, or check your printer’s manual for more info. Verify that your printer is not in Use Printer Offline mode.
