How do I restore the network settings on the HP Color LaserJet Pro M255 M256?

For a 2-line control panel printer, remove the USB cable, then press and hold the Wireless button until the Ready LED and Attention LED start blinking simultaneously, then release the button. For a touchscreen control panel printer, go to the Setup menu, select Network Setup, and then select Restore Defaults/Restore Network Settings. The printer will automatically restore network defaults and restart. (Page 9)
