How can I temporarily disable the Windows Firewall to diagnose if it's causing the issue?

As a troubleshooting step, you can temporarily disable the Windows Firewall to see if it's blocking communication. Open Control Panel > System and Security > Windows Defender Firewall. Click 'Turn Windows Defender Firewall on or off' and select 'Turn off Windows Defender Firewall (not recommended)' for both private and public networks. After testing, remember to re-enable the firewall for security reasons. If disabling the firewall resolves the issue, you'll need to configure firewall rules to allow printer traffic.
