This post is a reference for me in case in the future I have to change again the settings of my wireless HP printer. I had to change today my wireless settings as I have a new wireless router and wanted to use new SSID. The old router is a repeater-bridge now with the old SSID.
1. Restore the factory-set default settings
Follow these steps to restore the product’s factory default settings.
1. Press the Power button to turn off the product.
2. Press the Power button to turn on the product.
3. The product begins to initialize.
4. During init press and hold the Cancel button and the Wireless button (in this order) for 10 to 15 seconds (until it print a “Self Test / Device Configuration” page), and then release both buttons.
NOTE: LED lights blink until both buttons are released. The factory default settings are restored.
2. Change Wireless Printer Settings
1. Connect to the Ad Hoc Printer Network of the Printer.
2. You should edit the Ad Hoc Printer Network Connection on the client: “IPv4 Settings” -> “Method: Link-Local Only”
3. Maybe you have to “Disconect and Connect” until you can ping the printer.
4. To get the printer IP type on the terminal “arp -a” and you will see the IP of the printer.
5. Goto the http site of the printer with the ip. (Example http://3.3.3.3)
Webui for the printer
Once you are in the Printer Web-Interface, go to “Networking” and configure your wireless network.
Once it’s configure and working, you should be able to ping the printer in your network after disconnecting from Ad hoc printer Network and connecting to your normal wireless network.
In Linux Mint it is just 2 clicks to configure the printer, actually you do not have to configure anything like IP or driver…The world has changed in Linux :-)

I tried pressing and hold the Cancel button and the Wireless button (in this order) for 10 to 15 seconds during Initialization process, to print a “Self Test / Device Configuration” page which never printed.
Please, what else can be done to print the Device Configuration page, in order to reset the IPv4 on the HP Laser Jet Professional P 1102w?
Thank you.

That didn’t work for me either. The “answer” above is direct from the HP website. Our printers may have taken a power surge or something.

I pay a visit every day a few sites and information sites to read posts, but this weblog
offers quality based writing.

Thank you sir! Solved the factory reset problem. Other suggestions from HP support sites didn’t reset my printer. As soon as it reset my wireless was working again!

Jibberish.
Is this this written for Linux users or some other obscure group?
What is “Ad Hoc Printer Network of the Printer.”,
What is “client”?
I don’t want an associate’s degree in computer networking from ECPI.
I just want to connect my printer to wifi.
