## **1. Introduction**

The Windows Firewall is designed to protect your computer from unauthorized access, viruses, and malware. However, this same security can sometimes block legitimate devices like printers from communicating with your PC. This can result in printer not detected errors, offline status, failed print jobs, and more.

Firewall-related issues are especially common when setting up a **wireless printer**, installing **new printer drivers**, or sharing a printer over a **local network**. Understanding how to work with Windows Firewall is crucial to resolving these errors efficiently.

## **2. How Windows Firewall Interacts with Printers**

The Windows Firewall controls the flow of data to and from your computer. When you install a printer—especially a **network or wireless printer**—it attempts to communicate using certain **ports and protocols**.

If the firewall is too restrictive or hasn’t been configured correctly, it may **block incoming or outgoing printer traffic**, leading to errors such as:

* “Printer Not Found”
* “Printer Offline”
* “Cannot Connect to Printer”
* “Spooler Error”
* “Print Job Stuck in Queue”

These errors usually indicate that the printer is being **blocked by the firewall**, either fully or partially.

## **3. Common Printer Errors Caused by Firewall Settings**

Some of the most common error messages or behaviors related to Windows Firewall include:

* **Printer not detected on the network**
* **“Access denied” when trying to connect to shared printer**
* **Cannot install printer driver**
* **Scan to PC fails**
* **Printer software cannot communicate with the device**
* **HP Smart or Epson Connect not launching properly**

Firewall settings can prevent the printer from sending data to the PC or vice versa, especially if the **File and Printer Sharing** feature is not allowed.

## **4. Step-by-Step Fixes**

Let’s walk through how to resolve these firewall-related errors.

### **A. Check Windows Firewall Settings**

1. Press `Windows + R`, type `control`, and press Enter.
2. Go to **System and Security > Windows Defender Firewall**.
3. Click **“Allow an app or feature through Windows Defender Firewall.”**
4. Click **“Change settings.”**
5. Scroll and ensure **“File and Printer Sharing”** is checked for **Private and Public** networks.

> ✅ If it's unchecked, check both boxes and click OK.

### **B. Allow Printer Communication Through the Firewall**

1. Go back to **Windows Firewall Settings**.
2. Click **Advanced Settings** on the left panel.
3. In the Windows Firewall with Advanced Security window, click on **Inbound Rules**.
4. Look for rules labeled **File and Printer Sharing (Echo Request - ICMPv4-In)**, **Spooler Service**, or **Remote Printing**.

Make sure these rules are **Enabled**. If not:

* Right-click the rule > Click **Enable Rule**.

You can also create a new rule manually if needed.

### **C. Manually Create Firewall Rules**

1. Open **Windows Defender Firewall with Advanced Security**.
2. Click **Inbound Rules > New Rule**.
3. Select **Port** and click Next.
4. Choose **TCP**, and specify the ports:

TCP Ports: 139, 445  
UDP Ports: 137, 138

5. Click **Allow the connection**, then Next.
6. Apply the rule to all profiles: Domain, Private, and Public.
7. Name the rule: e.g., “Printer Port Rule”.

Repeat the steps for **Outbound Rules** as well.

### **D. Configure File and Printer Sharing**

1. Go to **Control Panel > Network and Sharing Center**.
2. Click **Change advanced sharing settings**.
3. Expand **Private** and **Guest or Public** settings.
4. Turn on:

* **Network Discovery**
* **File and Printer Sharing**

5. Scroll to the **All Networks** section:

* Turn on **sharing** so anyone with access to the network can print.
* Disable **password protected sharing** if you face access issues.

### **E. Troubleshoot Printer Software**

Sometimes, firewall settings interfere with printer utilities like HP Smart or Epson Connect.

1. Reinstall the printer software.
2. Allow the software through the firewall when prompted.
3. If blocked, go to **Firewall > Allowed apps**, click **Allow another app**, and browse to your printer software.

### **F. Restart Print Spooler Service**

If the firewall has disrupted the spooler service, restart it:

1. Press `Windows + R`, type `services.msc`, and press Enter.
2. Scroll to **Print Spooler**, right-click, and choose **Restart**.
3. Ensure the **Startup Type** is set to **Automatic**.

## **5. Advanced Fixes**

If the above steps didn’t work, try these advanced solutions.

### **A. Use Windows Troubleshooter**

1. Go to **Settings > Update & Security > Troubleshoot**.
2. Click **Additional troubleshooters**.
3. Select **Printer** and run the troubleshooter.
4. Follow on-screen instructions to fix errors related to the firewall or network.

### **B. Temporarily Disable Firewall for Testing**

⚠️ **Only use this step temporarily. Always turn the firewall back on afterward.**

1. Open **Windows Security > Firewall & network protection**.
2. Click on the active network (Private or Public).
3. Toggle **Firewall off**.
4. Try printing or scanning.
5. If it works, the firewall was blocking the printer.

Now re-enable the firewall and properly allow the printer as described earlier.

### **C. Check Third-Party Firewall or Antivirus Software**

Sometimes, **McAfee, Norton, Bitdefender**, or other third-party firewalls block printers even if Windows Firewall is set correctly.

1. Open your security software.
2. Go to **Firewall Settings**.
3. Look for blocked apps or ports.
4. Allow printer apps and ports manually.

## **6. Firewall Settings for Network Printers**

For wireless or Ethernet network printers, open these **common ports**:

* **UDP 161–162** (SNMP – Printer status info)
* **TCP 9100** (RAW printing)
* **TCP 631** (IPP printing)
* **TCP 515** (LPD printing)
* **TCP/UDP 137–139, 445** (Windows sharing)

Refer to your printer’s documentation to identify which ports it uses, and ensure those are allowed in the firewall.

## **7. Specific Printer Brands & Firewall Fixes**

Here’s how to fix firewall issues for some popular brands.

### **HP Printers**

* Use **HP Print and Scan Doctor** to detect firewall issues.
* Allow `hpnetworkcommunicator.exe` and `hpwuschd2.exe` through the firewall.

### **Epson Printers**

* Allow `EpsonNet Setup` and `Epson Event Manager` through the firewall.
* Use Epson’s connectivity software to troubleshoot.

### **Canon Printers**

* Allow **Canon IJ Network Tool** and **Canon Printer Utility** through the firewall.
* Open TCP/UDP ports specific to Canon models.

### **Brother Printers**

* Brother provides specific port lists—check support site.

## **8. Safety Tips While Adjusting Firewall Settings**

* Never **disable the firewall permanently**.
