To set up WiFi on an HP printer, you can use one of several methods depending on your printer model and router capabilities:

1. **Wireless Setup Wizard (for printers with a display):**
– Access the printer’s control panel or touchscreen.
– Go to “Setup” or “Network Settings.”
– Select “Wireless Setup Wizard.”
– Choose your WiFi network from the list.
– Enter the WiFi password using the printer interface.
– Wait for confirmation that the connection is successful[1].

2. **WPS (WiFi Protected Setup) Method:**
– Press the WPS button on your router.
– Within 2 minutes, press the WPS button on your printer (or select WPS Push Button through the printer’s network settings menu).
– The printer will connect automatically, confirmed by a solid WiFi light or message on the printer display.
– This method avoids manually entering WiFi passwords and works best with printers without a display[1][2][5].

3. **Using the HP Smart App (via computer or phone):**
– Ensure your computer or phone is connected to the target WiFi network.
– Download and install the HP Smart app.
– Open the app, sign in, and add your printer.
– In the app, navigate to printer “Settings” > “Network Setup.”
– Choose your WiFi network and enter the password.
– Connect the printer to WiFi through the app interface[3][4].

4. **USB Setup Method (for printers without displays):**
– Connect the printer to your computer via USB.
– Download and run the HP printer software or HP Smart app.
– Use the software wizard to set up the wireless connection.
– Disconnect the USB once the WiFi setup is complete[1].

**Important tips:**
– Make sure the printer is close to the router during setup.
– Use the 2.4 GHz WiFi band if your printer doesn’t support 5 GHz.
– If your printer supports HP Auto Wireless Connect, you can let it automatically receive network settings during installation[1][5].

Choosing the best method depends on your printer model and router features, but the Wireless Setup Wizard and WPS methods are usually the fastest and simplest for most HP printers. The HP Smart app provides a user-friendly alternative if you prefer using a computer or phone[1][3][4].
