Welcome to the HP support community.

I understand that you are trying to connect the printer to the WiFi using your phone, I am glad to assist you.

Install the HP Smart app

• Get the HP Smart app for Android, Apple iOS or iPadOS, Windows, and Mac.
• Download the HP Smart app from 123.hp.com (Android, Apple iOS, iPadOS),
• If you are prompted to sign in with Microsoft to use the app across devices, you can sign in or click No, thanks to continue.
• NOTE: Disconnect from a Virtual Private Network (VPN) connection before downloading.
• If you are setting up HP Smart for the first time, you must create or sign in to an HP account to access all printer functions.

Set up your printer using the HP Smart app

• Add your printer to HP Smart and follow the guided setup to connect to your computer or mobile device.
• If you are setting up the printer on a Wi-Fi network, prepare the printer for setup.
• Place the printer and the computer or mobile device near the Wi-Fi router.
• Turn on Wi-Fi on your computer or mobile device and connect to your network. If the computer is connected to the network with an Ethernet cable, temporarily disconnect the cable and use the Wi-Fi connection during the setup.
• Enable Bluetooth on the computer or mobile device so that HP Smart can detect the printer during the setup.
• For Windows computers, turn on Windows Update to make sure Windows is always up to date.
• After installing HP Smart for iOS and Android, enable the mobile device location service and allow the app to use your location to detect the printer and offer solutions during setup.
• Open HP Smart.
• If this is the first time you are opening HP Smart, the app attempts to detect and set up the printer. Follow the guided setup screens to complete the printer setup.
• If this is not the first time you are opening HP Smart, click Add Printer or the plus sign to find the printer. Follow the guided setup screens to complete the printer setup.
• Restore Wi-Fi setup mode.
• Printers without a touchscreen display or menu: Go to Restore Wi-Fi setup mode on your HP printer to restore default settings by pressing the buttons on your printer.
• Within two hours, close then re-open HP Smart, and then add the printer again.
• Follow the guided setup screens to complete the printer setup.
