Hi @Batbaby, Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding Printer connectivity!  

We're thrilled to have the opportunity to assist you and provide a solution.

Try these steps based on your connection type:

Check Connection Type

Are you using USB, Wi-Fi, or Bluetooth?

If USB Connection:

Check the USB Cable

• Ensure the cable is properly connected to both the printer and computer
• Try a different USB port on your computer
• If possible, use a different USB cable

Reinstall the Printer Driver

• Go to HP Support
• Search for "HP LaserJet MFP M139we"
• Download & install the latest Full Feature Software and Driver
• Restart your computer & printer

Set as Default Printer

• Windows: Go to Settings > Devices > Printers & Scanners, select your printer, and click Set as Default
• Mac: Go to System Preferences > Printers & Scanners, add the printer, and set it as default

If Wireless (Wi-Fi) Connection:

Reconnect Printer to Wi-Fi

• Press and hold the Wi-Fi button on the printer for 5 seconds until the Wi-Fi light blinks
• Use HP Smart App to reconnect the printer to the same Wi-Fi as your computer

Restart Devices

• Restart your printer, computer, and Wi-Fi router

Check Firewall Settings

• Ensure firewall or antivirus isn’t blocking the printer connection

If Bluetooth Connection:

• Your printer does NOT support Bluetooth, so use USB or Wi-Fi instead

Run HP Print and Scan Doctor (Windows Only)

1. Download HP Print and Scan Doctor from here
2. Run the tool and follow the instructions to diagnose the issue

If your printer still won’t connect, let me know:

• Your Windows version (Windows 10/11)?
• Are you using USB or Wi-Fi?
• Any error messages on the printer or PC?

I'll guide you further! 😊
