To set up your HP printer to WiFi, you can use one of the following main methods depending on your printer model and setup preferences:

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

2. **Using the WPS Button (if your router supports WPS and your printer has a WPS button):**
– Press the WPS button on your router.
– Within 2 minutes, press the WPS button on your printer.
– The printer will connect automatically; a solid WiFi light usually indicates success[1].

3. **Using the HP Smart App (works with both phones and computers):**
– Make sure your printer is on and near the WiFi router.
– Connect your phone or PC to your WiFi network.
– Download and install the HP Smart app.
– Open the app, sign in or create an HP account.
– The app should detect your printer; if not, add it manually.
– Go to “Settings” > “Printer Settings” > “Network Setup.”
– Select your WiFi network and enter the password.
– Tap “Connect”; the printer will join your wireless network[2][3].

4. **Using USB Setup (for printers without displays):**
– Connect your printer to your computer with a USB cable.
– Run the HP software or HP Smart app.
– Use the software’s instructions to select your WiFi network and enter the password.
– Complete the setup and disconnect the USB cable[1].

Additional tips:
– Ensure the printer is within WiFi range.
– Confirm you are connecting to a 2.4 GHz network if your printer does not support 5 GHz.
– Have your WiFi network name (SSID) and password handy.
– For printers without a display or WPS, the HP Smart app method is the simplest[1][2].

If you encounter issues, pressing and holding the Wireless button on the printer to reset the wireless settings and then retrying the setup can help[4].

These steps cover most HP printers, including DeskJet and All-in-One models. For detailed visual guidance, HP also provides video tutorials[2][3][5].
