To change the Wi-Fi network on your HP printer, you generally need to access the printer’s wireless settings and connect it to the new network either manually or using WPS (Wi-Fi Protected Setup). Here are the common methods:

1. **Using the Printer Control Panel Wireless Setup Wizard** (works if your printer has a touchscreen or menu):
– On the printer, go to the **Setup** or **Network** menu.
– Select **Wireless Setup Wizard** or similar (like Network Setup).
– The printer will scan for available Wi-Fi networks.
– Select your new Wi-Fi network from the list.
– Enter the network password when prompted.
– Follow any on-screen instructions to complete the setup[2][3][4].

2. **Using WPS Button Mode** (if your router and printer support WPS):
– On the printer, enable the WPS function by navigating to the **Wireless** or **Network** menu and selecting **Wi-Fi Protected Setup**.
– Within two minutes, press the **WPS button** on your wireless router.
– The printer will then automatically connect to the new Wi-Fi network without needing a password[1][4].

3. **Using the HP Smart App**:
– Open the HP Smart app on your computer or smartphone.
– Add your printer by tapping the “+” icon.
– Follow the instructions to connect the printer to the new Wi-Fi network[3].

If your printer doesn’t have a touchscreen or these options, refer to your specific model’s user guide or HP’s support website for model-specific instructions.

**Note:** After changing the network, ensure your computer or device you print from is on the same Wi-Fi network to maintain printing functionality[4].
