What this means

When the HP Smart app says printer not found, your phone, tablet, or computer cannot detect the printer over your network or via Bluetooth. They are simply failing to talk to each other.

Your printer is rarely broken or unplugged. It is usually turned on and working fine, but a software block, network setting, or permission issue hides it from your device.

Check your network for communication barriers. Different Wi-Fi bands, guest networks, active VPN software, and router settings like AP isolation block the signals the app needs. Location permissions matter too, because the app requires them to scan for Bluetooth and Wi-Fi.

Common causes

  • The phone and printer are connected to different Wi-Fi bands or networks.
  • Location services or Bluetooth permissions are disabled on the mobile device.
  • The printer is not currently in wireless setup mode.
  • Network isolation or AP isolation is enabled on the Wi-Fi router.
  • The printer's wireless signal is out of range of the router.
  • A VPN or security application is blocking local network discovery.
  • Temporary software glitches in the mobile app or printer network stack.

What to check first

  1. 1Verify the printer is powered on and the status lights are active.
  2. 2Check that your mobile device or computer is actively connected to Wi-Fi.
  3. 3Confirm you know your wireless network name and password.

Step-by-step fix

  1. 1

    Check Wi-Fi Network Connection

    Make sure your mobile device or computer is connected to the same local Wi-Fi network that you want the printer to use.

    Avoid using guest networks, as they intentionally isolate connected devices.

  2. 2

    Enable Bluetooth and Location Services

    Turn on Bluetooth and grant location permissions to the HP Smart app in your device settings. The app requires these permissions to scan for nearby wireless hardware.

    Some operating systems require location permissions enabled just to scan for local Wi-Fi devices.

  3. 3

    Restart All Devices

    Turn off your printer, unplug your Wi-Fi router, and reboot your phone or computer. Wait one minute, plug the router back in, wait for internet access to return, and then power on the printer and device.

  4. 4

    Put Printer in Setup Mode

    Reset the network settings on the printer to place it back into setup mode. On many models, this is done by holding the Wireless and Cancel buttons until the wireless light flashes.

  5. 5

    Disable Active VPN Services

    Turn off any active VPN applications, third-party firewalls, or security suites on your device, as they intercept local network broadcast packets.

  6. 6

    Clear App Cache and Reinstall

    Close the HP Smart app completely. Clear its cache through your device system settings, or uninstall and reinstall the app if discovery continues to fail.

  7. 7

    Check Router Isolation Settings

    Log into your router administration page using a web browser and ensure that AP Isolation, Client Isolation, or Wireless Isolation is disabled.

  8. 8

    Use USB Cable for Setup

    Connect the printer directly to a computer using a USB cable temporarily to configure the wireless settings through the HP Smart app, then disconnect the USB cable.

When to contact a professional

Call your internet service provider or network administrator. You need them if your router uses enterprise grade security, virtual local area networks, or a captive portal that blocks local device communication and cannot be reconfigured.
