Sharing a printer, especially a reliable Brother printer, across a home or small office network is a convenient way to streamline tasks and save resources. However, encountering issues where you can’t see your brother’s printer on your computer can be incredibly frustrating. This comprehensive guide will delve into the common reasons behind this problem and provide step-by-step troubleshooting methods to help you regain printer access.
Understanding the Basics: Network Printer Communication
Before diving into specific solutions, it’s essential to understand how a network printer communicates with your computer. Your Brother printer, when connected to a network, becomes a node within that network. Your computer needs to “discover” this node and establish communication to send print jobs. This discovery and communication rely on various protocols and network settings that, if misconfigured, can lead to visibility issues.
The Role of Network Protocols
Network protocols are sets of rules that govern how devices on a network communicate. Common protocols used for printer sharing include TCP/IP, Bonjour (primarily for Apple devices), and WSD (Web Services for Devices). If one of these protocols isn’t functioning correctly, your computer may fail to detect the printer.
IP Addresses and Network Configuration
Each device on your network, including your printer and computer, is assigned a unique IP address. These addresses allow devices to locate and communicate with each other. If the IP address of the printer is incorrectly configured or conflicts with another device on the network, it can prevent your computer from seeing the printer. Similarly, incorrect network settings on your computer, such as a mismatched subnet mask or gateway address, can also disrupt communication.
Common Causes: Why Your Brother Printer Might Be Invisible
Numerous factors can contribute to your computer’s inability to see your Brother printer. Understanding these causes is the first step toward resolving the issue.
Network Connectivity Problems
The most basic, yet often overlooked, reason is a simple network connectivity problem. This could range from a loose cable to a malfunctioning router.
Check physical connections: Ensure that both your computer and the Brother printer are properly connected to the network. This means checking the Ethernet cables (if applicable) or confirming that both devices are connected to the same Wi-Fi network. Look for lit indicators on the printer’s Ethernet port or the Wi-Fi router to confirm a connection.
Router issues: Your router acts as the central hub of your network. If the router is experiencing problems, such as a temporary outage or incorrect settings, it can prevent devices from communicating with each other. Try restarting your router by unplugging it for 30 seconds and then plugging it back in. Also, verify that your router’s firmware is up to date.
Driver Issues: Outdated, Corrupted, or Missing
Printer drivers are software programs that allow your computer to communicate with the printer. An outdated, corrupted, or missing driver is a common culprit behind printer visibility problems.
Outdated drivers: Printer manufacturers regularly release updated drivers to improve performance, fix bugs, and ensure compatibility with new operating systems. Using an outdated driver can lead to communication issues.
Corrupted drivers: Driver files can become corrupted due to various reasons, such as software conflicts or incomplete installations. A corrupted driver can prevent your computer from recognizing the printer.
Missing drivers: If you recently upgraded your operating system or reinstalled Windows, the printer driver might not have been installed correctly or at all.
Firewall and Security Software Interference
Firewalls and security software are designed to protect your computer from malicious threats. However, they can sometimes be overzealous and block legitimate network traffic, including communication with your printer.
Firewall settings: Your firewall might be blocking the ports that the printer uses to communicate with your computer.
Antivirus software: Some antivirus programs can also interfere with network communication.
Printer Sharing Settings and Permissions
Proper printer sharing settings are crucial for allowing other computers on the network to access the printer. If these settings are not configured correctly, your computer might not be able to see the printer.
Printer sharing enabled: Make sure that printer sharing is enabled on the computer to which the Brother printer is directly connected.
Permissions: Check the permissions granted to other users on the network. Ensure that the appropriate users have permission to access and use the printer.
IP Address Conflicts and Configuration
As mentioned earlier, IP address conflicts can disrupt network communication. If two devices on the network are assigned the same IP address, it can lead to errors and prevent your computer from seeing the printer.
Static vs. Dynamic IP Addresses: Understand whether your printer is using a static IP address (manually assigned) or a dynamic IP address (assigned by the router). Dynamic IP addresses can change over time, which might cause connectivity issues if your computer is still trying to connect to the old address.
DHCP Server: The DHCP (Dynamic Host Configuration Protocol) server on your router automatically assigns IP addresses to devices on the network. Ensure that the DHCP server is enabled and functioning correctly.
Troubleshooting Steps: Making Your Brother Printer Visible Again
Now that we’ve covered the common causes, let’s move on to the troubleshooting steps you can take to resolve the issue.
Basic Checks and Network Verification
Start with the most basic checks to rule out simple problems before moving on to more complex solutions.
Restart everything: Restart your computer, your Brother printer, and your router. This can often resolve temporary glitches and refresh network connections.
Ping the printer: Use the “ping” command in the Command Prompt (Windows) or Terminal (macOS) to test connectivity to the printer’s IP address. If the ping fails, it indicates a network connectivity problem. To find the printer’s IP address, you can usually print a network configuration report from the printer’s control panel.
Verify network connection: Ensure that both your computer and the printer are connected to the same network. Check the Wi-Fi network name or Ethernet cable connections.
Driver Reinstallation and Updates
Updating or reinstalling the printer driver is often a necessary step to resolve visibility issues.
Download the latest driver: Visit the Brother support website and download the latest driver for your specific printer model and operating system.
Uninstall the existing driver: Before installing the new driver, uninstall the existing driver from your computer. In Windows, you can do this through the “Devices and Printers” section in the Control Panel.
Install the new driver: Run the downloaded driver installation file and follow the on-screen instructions.
Firewall Configuration and Exceptions
Adjusting your firewall settings to allow communication with the printer can often resolve visibility problems.
Allow printer communication: Add an exception to your firewall for the Brother printer. This typically involves allowing communication on specific ports used by the printer. Consult your printer’s documentation or the Brother support website for the correct ports to allow.
Temporarily disable the firewall: As a test, temporarily disable your firewall and try to access the printer. If this resolves the issue, it confirms that the firewall is blocking communication. Remember to re-enable your firewall after testing.
Printer Sharing Settings and Permissions Adjustment
Verify and adjust the printer sharing settings to ensure that your computer has permission to access the printer.
Enable printer sharing: On the computer to which the Brother printer is directly connected, ensure that printer sharing is enabled. In Windows, you can find this setting in the “Advanced sharing settings” section of the Network and Sharing Center.
Check user permissions: Verify that your user account has permission to access the printer. You can do this in the printer’s properties dialog box, under the “Security” tab.
IP Address Configuration and Conflict Resolution
Addressing IP address conflicts and ensuring proper IP address configuration is critical for network printer visibility.
Assign a static IP address: Consider assigning a static IP address to your printer. This will prevent the IP address from changing dynamically and potentially causing connectivity issues. You can configure a static IP address through the printer’s control panel or web interface.
Check for IP address conflicts: Use a network scanning tool or your router’s administration interface to identify any IP address conflicts on your network. If you find a conflict, change the IP address of one of the conflicting devices.
Using Brother’s Printer Driver Installation Tool
Brother provides a utility called the “Printer Driver Installation Tool” that can automatically detect and install the correct printer driver for your computer. This tool can simplify the driver installation process and resolve compatibility issues. You can download this tool from the Brother support website.
Network Discovery and Bonjour Service (for macOS)
For macOS users, the Bonjour service plays a crucial role in discovering network printers.
Ensure Bonjour is enabled: Verify that the Bonjour service is enabled on your Mac. This service is usually enabled by default, but it’s worth checking to make sure it’s running.
Check network discovery settings: Ensure that network discovery is enabled in your Mac’s System Preferences. This allows your Mac to discover devices on the network, including your Brother printer.
Advanced Troubleshooting: When Nothing Else Works
If you’ve tried all the basic and intermediate troubleshooting steps and your computer still can’t see your Brother printer, it’s time to move on to more advanced solutions.
Firmware Update
Outdated printer firmware can sometimes cause compatibility issues and prevent network communication. Check the Brother support website for firmware updates for your printer model. Follow the instructions provided by Brother to update the firmware.
Resetting the Printer to Factory Settings
As a last resort, you can try resetting the printer to its factory default settings. This will erase all custom settings, including network configurations, and restore the printer to its original state. Consult your printer’s manual for instructions on how to perform a factory reset. Be aware that you will need to reconfigure the printer’s network settings after performing a factory reset.
Checking for Hardware Issues
While less common, hardware issues can also prevent your computer from seeing the printer.
Ethernet port issues: If you’re using an Ethernet connection, try a different Ethernet cable and a different port on your router or switch.
Wi-Fi adapter issues: If you’re using a Wi-Fi connection, ensure that the printer’s Wi-Fi adapter is functioning correctly. Try connecting the printer to the network using an Ethernet cable to see if that resolves the issue.

Why can’t my computer detect my brother’s printer on the network?
There are several reasons why your computer might not be detecting the printer, even if it’s properly connected to the network. One common cause is that network discovery is disabled on your computer. This setting allows your computer to “see” other devices on the network, including printers. Also, incorrect IP configurations or firewall settings on your machine or the printer’s network can prevent them from communicating, even if they’re on the same network.
Another potential issue is that the printer driver is either not installed on your computer or is outdated. This can hinder communication between your computer and the printer. Driver problems can also prevent automatic detection of the printer. Furthermore, problems with the printer’s connection to the network, such as a loose cable or a faulty Wi-Fi connection, could also be preventing your computer from seeing the printer.
Is it possible the printer isn’t actually on the network, even if it seems to be?
Yes, it’s entirely possible. Even if the printer’s display indicates a network connection, it might not be correctly configured or actively participating in the network. Check that the printer’s IP address is valid within your network’s IP address range and that the printer’s subnet mask and gateway settings are correct. An incorrect IP address, conflicting with another device on the network, will prevent proper communication.
Also, the printer might be connected to a guest network or a different Wi-Fi network than your computer. Many routers provide separate networks, and devices on different networks generally cannot communicate with each other. Double-check that both the printer and your computer are connected to the same Wi-Fi network with the same SSID. Confirm the printer isn’t inadvertently connected through USB only, believing it to be network connected.
How do I check if network discovery is enabled on my Windows computer?
To check if network discovery is enabled, go to Control Panel, then Network and Internet, and finally Network and Sharing Center. Click on “Change advanced sharing settings” on the left-hand side. You should see options for Network discovery, File and printer sharing, and Public folder sharing. Ensure that “Turn on network discovery” is selected for the network profile you are currently using (either private or guest/public networks).
If network discovery is already enabled, try toggling it off and then on again. This can sometimes refresh the network settings and allow your computer to detect the printer. After making changes, restart your computer for the changes to take full effect. Also, make sure that the Function Discovery Resource Publication service is running in the Services window. If it’s not, set it to “Automatic” and start the service.
My firewall is on. Could that be blocking the printer?
Yes, your firewall could definitely be blocking communication with the printer. Firewalls are designed to protect your computer from unauthorized access, and they might mistakenly block legitimate network traffic, including printer communication. The firewall might be blocking the specific ports or protocols that the printer uses to communicate with your computer.
To check this, you can temporarily disable your firewall and see if that allows your computer to detect the printer. If it does, you’ll need to create an exception in your firewall settings for the printer. This usually involves allowing communication through specific ports (like port 9100 or LPR/LPD) or allowing communication with the printer’s IP address. Check your printer’s documentation to find the specific ports and protocols it uses.
How do I find the IP address of my brother’s printer?
There are several ways to find the printer’s IP address. The easiest method is usually to print a network configuration page directly from the printer. Look for an option like “Network Settings,” “Configuration Report,” or a similar term in the printer’s menu. This page will typically list the printer’s IP address, subnet mask, gateway, and other network-related information.
Alternatively, you can access the printer’s settings through a web browser if you know the printer’s name. Type `\\printername` in the Windows Run dialog (Windows Key + R), replacing `printername` with the printer’s shared name on the network. If successful, this may open the printer’s webpage, where you can locate the printer’s IP address in its configuration settings. Finally, if the printer is directly connected to the router, access the router’s administration panel (usually by typing its IP address in a browser) and look for a list of connected devices. The printer should be listed there with its IP address.
I’ve installed the printer driver, but it still isn’t working. What next?
Even after installing the driver, there could still be driver-related issues preventing the printer from working. First, ensure you’ve installed the correct driver version for your operating system (e.g., Windows 10 64-bit or macOS Monterey). If you’re unsure, download the latest driver from the printer manufacturer’s website, specifically the one that matches your operating system. A corrupted driver can also cause issues, so try uninstalling the existing driver completely and reinstalling it.
After reinstalling the driver, try manually adding the printer using its IP address. In Windows, go to Settings > Devices > Printers & scanners and click “Add a printer or scanner.” If the printer isn’t automatically detected, choose “The printer that I want isn’t listed” and then select “Add a printer using a TCP/IP address or hostname.” Enter the printer’s IP address and follow the prompts. This manual process can sometimes bypass driver-related detection problems.
Could the problem be with my router or network itself?
Yes, issues with your router or network configuration can definitely prevent your computer from detecting the printer. A faulty router or incorrect router settings can disrupt communication between devices on the network. Restarting your router is often the first troubleshooting step, as this can resolve temporary network glitches or configuration errors. Wait a few minutes after restarting the router before attempting to connect to the printer again. If the problem persists, consider updating your router’s firmware to the latest version as outdated firmware can contain bugs that affect network connectivity.
Additionally, some routers have settings that can inadvertently block communication between devices. Check your router’s settings to ensure that “AP Isolation” or “Client Isolation” is disabled. These settings are designed to prevent devices connected to the same Wi-Fi network from communicating with each other, and enabling them would prevent your computer from seeing the printer. Additionally, ensure that the router’s firewall settings aren’t overly restrictive and blocking the printer’s network traffic.
