To reconnect your HP printer to a new Wi-Fi network, you generally use the **Wireless Setup Wizard** on the printer’s control panel (if it has a touchscreen) or the HP Smart app. The basic steps are:

– On the printer, go to the **Wireless Setup Wizard** or a similar option in the **Network Settings** menu.
– Select your new Wi-Fi network from the list of available networks.
– Enter the new Wi-Fi password.
– Complete the connection process as prompted, and the printer should connect to the new Wi-Fi.

If your printer lacks a touchscreen, you can connect the printer to a computer via USB and change the Wi-Fi network using HP’s software on that computer.

Alternatively, you can use the **HP Smart app** on your phone or PC:
– Open the app and choose to add a printer.
– Follow the on-screen instructions to set up the wireless connection with the new Wi-Fi.

If your printer and router support WPS (Wi-Fi Protected Setup), you can also use the WPS push-button method to connect quickly.

After reconnecting, you may need to reinstall or update your printer’s connection on your computer or device to ensure it prints wirelessly[1][2][3][4].

Detailed steps from the Wireless Setup Wizard method:

1. On your HP printer’s control panel, find the **Wireless** or **Network** menu.
2. Select **Wireless Setup Wizard**.
3. From the displayed list of Wi-Fi networks, choose your new network.
4. Enter the Wi-Fi password using the printer keypad.
5. Complete the setup and confirm the connection (a wireless icon should appear solid).

If you have issues, restart your printer, router, and device, make sure you are within network range, and check the Wi-Fi password is correct[1][5].

This process applies to most HP printers released in recent years; for specific models, refer to the printer’s manual or HP’s website if you encounter model-specific differences.
