I have just set up my new printer/scanner and connected it wirelessly to my PC and it was working fine. I subsequently went into HP Support and it prompted me to install a software update, which I attempted but failed to complete.
Now when I go to operate the printer from my PC I get a message on screen stating that a custom password has been set for my printer, which it requires me to enter to access printer web interface. I have no idea what this password is or how to find it. the WiFi password on my router does not work. Help!!
