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.

Download and run HP Print and Scan Doctor .
Click Network, and then click Troubleshooting Firewalls.
Click the name of any firewall software that has an Enabled status, and then click Disable. Do this until all firewalls are disabled.
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.

note:
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.

Configure firewall settings in Windows Defender

Windows Defender is automatically installed on all computers with Windows 8 and later. If you are using the Windows Defender Firewall, follow the steps below to configure the firewall.

Step 1: Unblock HP programs

Open Windows Defender to manage programs that can send and receive information.

Open the Control Panel.
Click System and Security.
Click Windows Defender Firewall.
To see the programs that are allowed through your firewall, click Allow an app or feature through Windows Defender Firewall.
Scroll down until you see the HP programs available on your computer.
Make sure all HP programs are allowed for the type of network you are using (private or public).

To allow a program, first click Change settings at the top right, and then check the box in the column that applies to your network.

Step 2: Confirm HP printer ports have rules

Printers use ports to communicate with a computer. Rules create openings in the firewall for specific ports. To avoid issues with HP printers in the future, look for and enable rules to allow HP printer ports.

Go back to the main Windows Defender Firewall screen, and then click Advanced Settings.
On the left panel, click Outbound Rules.
Scroll to the right until you see the column labeled Remote Port, and then click Remote Port to sort it numerically.
Search the list for the following outbound rules. Make sure the protocol matches (TCP or UDP).

note:
Any missing ports are added in a later step to create rules.
- TCP 80
- TCP 139
- UDP 139
- UDP 161
- UDP 427
- TCP 443
- TCP 631
- UDP 3702
- UDP 5353
- TCP 8080
- TCP 9100
- TCP 9220
- TCP 9290
- TCP 9500
Make sure the rules you find are enabled. Enabled rules have a green check mark next to them.

To enable a rule that does not have a green check mark, select the rule, and then click Enable Rule in the right panel.
Repeat these steps for inbound rules. On the left panel, click Inbound Rules, and then sort and search the Local Port list for the following inbound rules, making sure they are enabled.
- TCP 80
- UDP 427
- TCP 443
- TCP 631
- UDP 3702
- UDP 5353
- TCP 8080
- TCP 9100

If you found and enabled every HP port, you do not need to continue to the next step. If you still experience problems, go to HP Customer Support to continue troubleshooting.

If you did not find every HP port, continue to the next step.

Step 3: Create rules for missing HP ports

Rules allow your printer to communicate with your computer even when the firewall settings change, such as setting up a new home network or increasing the firewall level when using a public network.

On the right panel, click New Rule...

note:
On the left panel, make sure you have selected the correct type of rule (inbound or outbound) for each creation.
Select Port, and then click Next.
Select UDP or TCP and Specific local ports, type the port number into the field, and then click Next.
If you only use a trusted, secure network, select Allow the connection, and then click Next.

If you use multiple networks or an unsecure network, select Allow the connection if it is secure, and then complete an additional step to authorize or block specific computers.
Check the boxes that match your network type, and then click Next.
Name the rule and add a description (optional), and then click Finish.
Repeat these steps to create a rule for any other missing HP ports.

Configure firewall settings in other security software

If your firewall is managed by another software application, go to the software manufacturer's support website for steps to change firewall settings.

Common security software websites:

BitDefender (in English)
Kaspersky (in English)
Avira (in English)
Avast (in English)
eScan (in English)
Norton (in English)
McAfee (in English)
AVG (in English)

Check each of the following firewall settings, and change them as necessary.

Your security software is up to date.
Your firewall settings have not been changed from default.
Your firewall strength is set to Medium when you are connected to your home network.
Your network is set as a Trusted Zone, if possible.
HP programs are listed as trusted programs, and are not blocked.
Firewall alert messages are enabled. If you install new HP software, your security software asks if you want to Allow, Permit, or Unblock. Always select this option for HP software.

If your security software has a Remember this action or Create a rule for this option, select it.

HP ports are not blocked. If necessary, create rules to allow the following HP ports.

Inbound Rules	Outbound Rules
TCP 80 TCP 443 TCP 631 TCP 8080	TCP 80 TCP 139 TCP 443 TCP 631 TCP 8080 TCP 9100 TCP 9200 TCP 9290 TCP 9500
UDP 427 UDP 3702 UDP 5353	UDP 139 UDP 161 UDP 427 UDP 3702 UDP 5353
