HP Printers - Firewall Blocking Driver Install or Printer Function (Windows)

This document is for HP printers and computers with Windows operating systems.
Firewall software helps block threats from outside your network, but some settings or configurations can block communication with network printers. Firewall settings might cause one of the following issues:
  • You are unable to install the printer software.
  • When you install the printer software, the printer cannot be found on the network.
  • Some functions of your printer work while others do not.
  • Your printer suddenly does not print.
  • The printer status displays as Not connected even though the printer is connected to the network.
To determine if your firewall is causing the issue, use HP Print and Scan Doctor to temporarily disable the firewall, and then configure the firewall using your security software, if necessary.

Step 1: Temporarily disable the firewall

Using HP Print and Scan Doctor, temporarily disable the firewall to determine if it is blocking driver installation or printer functionality.
  1. Download and run HP Print and Scan Doctor .
  2. Click Network, and then click Troubleshooting Firewalls.
    Clicking Network and Troubleshooting Firewalls
  3. Click the name of any firewall software that has an Enabled status, and then click Disable. Do this until all firewalls are disabled.
    Example of the Advanced Info window
  4. When all firewalls are disabled, install your printer software or try to use your printer.
    • If the installation completed, re-enable the firewall in the Print and Scan Doctor. For future installs, you can either temporarily disable the firewall each time, or you can continue to the next step and configure the firewall to allow HP programs.
    • If the printer functionality returned, re-enable the firewall in the Print and Scan Doctor, and then continue to the next step and configure the firewall to allow HP programs.
    • If the installation failed or your printer still does not function properly, the firewall software is not causing the issue. Re-enable the firewall in the Print and Scan Doctor, and then search for the issue on HP Customer Support to continue troubleshooting.
Using multiple firewalls at the same time will not make your computer any safer and can cause problems. If more than one firewall is enabled, disable all but one firewall.

Step 2: Configure the firewall

Anti-virus and computer security programs, such as McAfee and Norton, include firewall software that monitors communications to your computer for threats. Follow the steps in the section that applies to your security software.
