In shared spaces like business centres, having a Wi-Fi printer can be incredibly convenient—until someone accidentally sends their documents to your printer! Fortunately, you can take steps to secure your printer and ensure it’s hidden from other users on the same network. Here’s how you can protect your device and prevent unwanted print jobs.
Disclaimer: there are so many printers, and so many ways to configure them: some easy, some difficult! If this article is all techno-babble to you, do reach out to your local tech-friendly support person for assistance, and/or try a Google search such as “How do I hide my printer <make> <model> on a wi-fi network?”
1. Enable Private IP Addressing
Modern routers often include a feature called “Client Isolation” or “Private Network.” This setting prevents devices connected to the same Wi-Fi from seeing or communicating with each other.
How to do it:
- Log into your router’s admin interface.
- Look for “Client Isolation” under the Wi-Fi or network settings.
- Enable the feature to make your printer invisible to others on the network.
2. Assign a Static IP Address and Disable Broadcasting
Your printer likely has options to configure its network visibility. Assigning a static IP address makes it easier for you to connect while disabling features like “Wi-Fi Direct” or “mDNS” (Multicast DNS) hides it from others.
Steps to follow:
- Access the printer’s network settings via its control panel or web interface.
- Assign a static IP address.
- Disable broadcasting features that announce the printer’s presence to the network.
3. Create a Separate Network with VLANs
If your router supports VLANs (Virtual Local Area Networks), you can create a dedicated network just for your printer. This ensures it remains isolated from the primary Wi-Fi network used by others.
How it works:
- Set up a VLAN on your router and connect the printer to it.
- Configure access rules so only authorized devices can communicate with the VLAN.
4. Enable Printer Security Settings
Modern printers often come with built-in security options. Enable them to restrict who can access the printer.
What to do:
- Set a password for the printer.
- Require authentication for all print jobs.
- Limit access by MAC address to ensure only specific devices can connect.
5. Connect the Printer to a Private Network
For ultimate privacy, connect your printer to a separate Wi-Fi or wired network that only you can access. This could be a guest network on your router or a dedicated hotspot.
Pro Tip: If connecting to a different network isn’t possible, try tethering it to your computer instead of sharing it directly on the Wi-Fi network.
6. Configure Firewall Rules
Use your router or printer’s firewall settings to block incoming traffic from unauthorized devices. This adds an extra layer of protection against accidental or intentional connections.
7. Disable Universal Plug and Play (UPnP)
UPnP is a convenience feature that automatically makes devices discoverable on a network—but it’s not ideal in shared spaces. Disable it in your router and printer settings to keep your device hidden.
8. Share the Printer Through Your Computer
If you don’t want the printer connected to Wi-Fi at all, connect it to a computer using a USB or Ethernet cable. Then, share the printer through the computer’s settings and restrict access to authorized users.
Why Hiding Your Printer Matters
Keeping your printer private isn’t just about convenience—it’s about security. Unprotected printers on shared networks can become targets for unauthorized access, wasting resources and potentially exposing sensitive information.
By following these tips, you can enjoy the convenience of a Wi-Fi printer without the hassle of unexpected visitors in your print queue. So, go ahead—set it up, hide it, and print in peace!
Memorable takeaway: A little setup goes a long way—when it comes to shared networks, the best way to print is to stay hidden.
