Hi @Quan400,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand your HP DeskJet 4120e All-in-One Printer is having trouble completing the setup, here are several steps you can follow to resolve the issue:
 

1. Check Printer's Wireless Connection

• Ensure printer is in setup mode: If you're setting it up for the first time, the printer should automatically be in setup mode (indicated by a blinking blue wireless light). If it's not, restore setup mode by pressing and holding the Wireless and Cancel buttons on the printer for 5 seconds until the light starts blinking.
• Bring the printer close to the router: Ensure the printer is within range of your WiFi router.

2. Use the HP Smart App for Setup

• Make sure the HP Smart app is installed on your device (available for Windows, macOS, Android, and iOS).
• Open the HP Smart app and add the printer. The app will guide you through the setup process.

3. Restart Printer and Devices

• Power cycle the printer by turning it off, unplugging it for a minute, and then plugging it back in.
• Restart your computer or mobile device.

4. Ensure Internet Connection is Stable

• Verify that your WiFi network is working properly by testing other devices.
• Turn off mobile data if setting up via a mobile device to ensure it connects through WiFi only.

5. Disable VPN or Firewall Temporarily

• Turn off VPN if it's active during the setup process as it can interfere with communication between the printer and the network.
• Temporarily disable firewall settings on your device to allow smooth communication during setup.

6. Update Printer Firmware Update the firmware on an HP printer 

• If possible, connect the printer via USB to a PC and update its firmware using the HP Smart app or the HP website to ensure the latest version is installed.

7. Use an Alternate Setup Method

• If the wireless setup continues to fail, try setting up the printer using a USB connection to ensure the initial configuration goes through, and then switch to wireless afterward.
