Help and tips for Wi-Fi and connectivity (wireless model only)
If the software is unable to find your printer during setup, check the following conditions to resolve the issue.
| Potential Issue | Solution |
Printer Wi-Fi setup mode timed out. | If the Wireless light is not blinking blue, the printer might not be in Wi-Fi setup mode. Restart setup mode:
Note: Only 2.4 GHz connection supported. |
| Computer or mobile device too far from printer | Move your computer or mobile device closer to the printer. Your device might be out of range of the printer’s Wi-Fi signal. |
| Computer connected to a Virtual Private Network (VPN) or remote work network | Disconnect from a VPN before installing HP Smart software. You can’t install apps from the Microsoft Store when connected to a VPN. Connect to the VPN again after finishing printer setup. Note: Consider your location and the security of the Wi-Fi network before disconnecting from a VPN. |
| Wi-Fi turned off on computer (computer connected by Ethernet) | If your computer is connected by Ethernet, turn on the computer’s Wi-Fi while setting up the printer. You don’t need to disconnect the Ethernet cable |
| Bluetooth and location services are turned off on your mobile device | If setting up with a mobile device, turn on Bluetooth and location services. This helps the software find your network and printer. Note: Your location is not being determined and no location information is being sent to HP as part of the setup process. |
