HP DeskJet 3630 Wi-Fi Direct Password - connecting to Amazon Kindle Fire
I am trying to connect my Amazon Kindle Fire directly to my HP DeskJet 3630 (eg Kindle to printer and not via my router) to print some receipts.
When I turn on the Wi-Fi Direct button on the printer and then go to the Kindle Fire Wi-Fi settings I can see the W-Fi Direct option but when I press connect it asks for password and I have no idea what it is (it is 8 digits long).
I want to find out what the password and/or change it. The information that I printed the Wi-Fi Direct guide suggested that you can access the embedded web server on ip address http://192.168.223.1 but I cannot access it.
I downloaded the HP doctor and it gave me my router password (which I know) but not the Wi-Fi Direct password.
Is there a way I can access the printers settings to work out what the password for the Wi-Fi Direct is?
