HP printers are widely used for home and office printing due to their reliability, wireless connectivity, and advanced features. However, users may sometimes face an issue where HP printer network access is blocked by a firewall, preventing printing, scanning, or communication between the printer and computer. This problem commonly occurs after installing security software, updating the operating system, or changing network settings.
What Causes HP Printer Network Access to Be Blocked by Firewall?
A firewall is designed to protect your system from unauthorized access, but sometimes it may mistakenly block trusted devices like your HP printer. When this happens, your printer may appear offline, stop responding, or fail to connect over Wi-Fi.
Common causes include incorrect firewall permissions, outdated HP printer software, incomplete installation, or recent system updates that reset network rules.
Symptoms of HP Printer Firewall Blocking Issue
When the firewall blocks your HP printer, you may notice the following issues:
- HP printer shows offline even when connected
- Unable to print or scan over the network
- HP printer software cannot detect the printer
- Printer works on USB but not on Wi-Fi
- Repeated network or communication error messages
Identifying these signs helps in troubleshooting the issue effectively.
How to Fix HP Printer Network Printer Access Blocked by Firewall
Follow these steps carefully to unblock your HP printer and restore network access.
Check Firewall Settings on Your Computer
Firewalls may block HP printer services by default. Open your firewall settings and ensure that HP printer software is allowed to communicate through private and public networks.
Allow permissions for HP background services, printer discovery, and network communication to prevent access issues.
Temporarily Disable Firewall for Testing
To confirm whether the firewall is the cause, temporarily disable it and try printing again. If the printer works, the issue is firewall-related.
Once confirmed, re-enable the firewall and adjust the settings instead of leaving it disabled permanently.
Update HP Printer Software and Drivers
Outdated HP printer drivers can trigger firewall blocks. Updating the software ensures compatibility with the latest security rules.
An updated driver improves printer recognition, fixes network bugs, and prevents access conflicts caused by system updates.
Reinstall HP Printer Software
Corrupt or incomplete installation files can also lead to firewall conflicts.
Uninstall the existing HP printer software, restart your computer, and then reinstall it properly. During installation, allow all permissions requested by the system.
Check Network Connection and IP Address
Ensure your HP printer and computer are connected to the same network. If the printer’s IP address changes frequently, firewall rules may fail.
Setting a stable network connection helps the firewall recognize the printer as a trusted device.
HP Printer Login and Signup Issues
Many HP printers require users to log in or sign up through HP software to enable features like wireless printing and scanning.
If login or signup fails due to network restrictions, firewall settings may be blocking authentication services. Allow HP login services through your firewall to resolve this issue.

To avoid installation errors:
- Allow HP installer services through the firewall
- Run the installer as administrator
- Ensure stable internet connectivity
Proper activation ensures your printer functions correctly without network interruptions.
