I can't print and am getting error 79 on HP LaserJet Pro 400 color M451dw printer. Was trying to set up printing via wifi and that failed. Trying to get back to be able to print using USB cable.

I would try turning off the wireless router, restart the printer and if it comes to ready, go into the control panel of the printer and turn off wireless. 79 errors are often caused by network issues hence the need to turn the wireless off so the printer does not try to connect and error out before you can access menus through the control panel.
