🖨️ Printer Showing as Unavailable? Security Settings May Be Affecting It on Windows 10 & 11

You may notice that a printer appears unavailable even after checking power, connections, and restarting devices. In some situations, computer security settings—such as firewalls or antivirus programs—can limit how your printer communicates with Windows.

This article explains how security features can influence printer communication on Windows 10 and Windows 11, and outlines safe ways to review those settings without removing software or system protection.

🔍 How Security Software Can Affect Printer Communication

Security tools monitor network activity to protect your system. Occasionally, these tools may restrict printer communication—especially for printers connected through Wi-Fi or a local network.

Common Indicators

  • Printing worked previously and changed after a system or security update

  • The printer’s network address opens in a browser, but printing does not proceed

  • Printing resumes briefly when security protection is paused

These signs often indicate that printer traffic is being limited by security rules.

🧪 Step 1: Briefly Pause Security Protection (Testing Purpose Only)

⚠️ This step is for testing only. Protection should be re-enabled immediately after checking.

A. Windows Security Firewall

  1. Open Start → Settings → Privacy & Security

  2. Select Windows Security → Firewall & Network Protection

  3. Choose the active network type

  4. Temporarily switch the firewall off

  5. Try sending a document to print

  6. Turn the firewall back on right away

B. Third-Party Security Software

  1. Right-click the security software icon in the system tray

  2. Select the option to pause protection temporarily

  3. Try printing a document

  4. Re-enable protection immediately

🔧 Step 2: Allow Printer Communication Through Windows Firewall

If printing works while protection is paused, permissions can be adjusted:

  1. Go to Start → Settings → Windows Security → Firewall & Network Protection

  2. Select Allow an app through firewall

  3. Click Change settings

  4. Locate printer-related applications

  5. Enable access for both Private and Public networks

  6. If not listed, choose Allow another app and browse for the printer application

  7. Save changes and restart the computer

🔐 Step 3: Review Permissions in Third-Party Security Software

For non-Windows security tools:

  • Open the security application

  • Locate sections such as Firewall, Network Control, or Allowed Items

  • Add the printer’s network address to the allowed list

  • Allow printer-related background applications

  • If available, allow commonly used printer communication ports:

    • TCP 9100

    • TCP 631

    • TCP 515

    • UDP 161 / 162

Refer to official printer documentation for exact communication details.

🏠 Step 4: Check Network Profile Type

A private network profile allows devices to communicate more freely.

  1. Open Start → Settings → Network & Internet

  2. Select Wi-Fi or Ethernet

  3. Click the connected network

  4. Ensure the network profile is set to Private

✅ Final Notes

Security tools play an important role in protecting your system, but they can sometimes limit printer communication. Reviewing firewall and network permissions often restores normal printing behavior without changing drivers or removing software.

For printer-specific communication requirements, always rely on official guidance provided by the manufacturer.
