HP printers are widely used for printing, scanning, and copying in homes and offices. However, sometimes users face issues where the HP printer scanner is not working due to Windows Firewall settings. When the firewall blocks essential communication between your printer and computer, scanning features may stop functioning properly.
What Causes HP Printer Scanner Not Working with Windows Firewall?
Windows Firewall is designed to protect your system from unauthorized access. However, in some cases, it may block the HP scanning service or related network ports required for communication.
Common causes include:
- Firewall blocking HP scanning software
- Disabled Windows Image Acquisition (WIA) service
- Outdated HP printer drivers
- Network discovery turned off
- Incorrect installation of HP printer software
- HP printer not activated or properly configured
Understanding the cause helps in applying the correct fix.

1. Allow HP Printer Through Windows Firewall

If the app is not listed, click Allow another app and manually add the HP software.
2. Temporarily Disable Windows Firewall (For Testing)
To confirm the firewall is causing the issue:
