That innocent-looking printer in your Hampshire office corner could be your business’s biggest cybersecurity blind spot. While you’ve probably secured your computers and servers, many business owners overlook the fact that modern printers are essentially computers connected to your network: and cybercriminals know this.
Recent attacks have shown hackers using printers as entry points to steal sensitive data, launch ransomware attacks, and even spy on businesses. For Hampshire SMEs handling everything from client contracts to financial records, a compromised printer could spell disaster.
The good news? Securing your printers doesn’t require a computer science degree. With some straightforward steps, you can lock down these devices and protect your business from becoming another cybercrime statistic.
Why Your Printer Is a Cybercriminal’s Dream Target
Modern office printers aren’t just print machines: they’re sophisticated devices that store documents in memory, connect to your network, and often have internet access. This makes them attractive targets for several reasons:
They’re forgotten about. Most businesses secure their laptops and servers but completely ignore printer security, leaving an open door for attackers.
They store sensitive data. Printers temporarily store copies of everything they process, from payroll documents to client contracts.
They’re network gateways. Once hackers access your printer, they can use it as a stepping stone to reach other devices on your network.
They rarely get updated. Unlike computers that receive regular updates, many printers run outdated firmware with known security vulnerabilities.
Step 1: Lock Down Access to Your Printers
The first line of defence is controlling who can use your printers and when.
Set up user authentication for all print jobs. This means employees must enter a PIN or password at the printer before their documents print. It prevents sensitive documents from sitting unattended and stops unauthorised users from printing.
Create user groups with different printing permissions. Your accounts team might need access to financial printers, while general staff only need basic document printing.
Turn off printers outside business hours. There’s no reason your printer should be accessible at 2 AM when your Hampshire office is empty.
Disable guest printing completely. If visitors need to print something, they can email it to a staff member.
Step 2: Secure Your Network Connections
Your printer’s connection to your network needs the same protection as any other business-critical device.
Use encrypted connections only. Ensure all communication between computers and printers uses secure protocols. Avoid connecting printers to public Wi-Fi or unsecured networks.
Place printers behind your firewall and configure it to block unnecessary network traffic. Only allow communication from trusted devices within your business.
Disable unnecessary connectivity features. If you don’t need wireless printing, turn it off. The same goes for cloud printing services, email functionality, and web browsing capabilities.
Separate your printers on the network. Consider creating a separate network segment for printers to limit what they can access if compromised.
Step 3: Keep Firmware Updated and Secure
Printer manufacturers regularly release firmware updates that patch security vulnerabilities: but they don’t install themselves.
Check for updates monthly. Make printer firmware updates part of your regular IT maintenance routine. Treat them as seriously as you would computer updates.
Enable automatic updates where possible, but test them first on a non-critical printer to ensure they don’t cause operational issues.
Change default passwords immediately. Every printer ships with default admin credentials that are easily found online. Change these during initial setup: use strong, unique passwords that aren’t used elsewhere in your business.
Document your settings. Keep a record of security configurations so you can restore them if a printer needs factory resetting.
Step 4: Monitor and Track Printing Activity
You can’t protect what you can’t see, so monitoring your printer usage is essential.
Install print tracking software to record who prints what, when, and where. This creates an audit trail and helps identify unusual activity.
Set up alerts for suspicious behaviour, such as large print jobs outside business hours or attempts to access restricted functions.
Review logs regularly. Make checking printer activity part of your monthly security review: look for patterns that might indicate a problem.
Monitor paper and toner usage. Unexpected increases in consumption could indicate unauthorised printing or a compromised device.
Step 5: Protect Sensitive Data in Transit and Storage
The documents passing through your printers need protection at every stage.
Use data encryption for all print jobs containing sensitive information. This protects documents as they travel from computers to printers.
Enable secure print release, where documents only print when the user is physically at the printer and authenticates themselves.
Configure automatic data deletion to remove document copies from printer memory after processing. Set the shortest retention time that still meets your business needs.
Implement content filtering to prevent certain types of sensitive data from being printed without special authorisation.
Step 6: Train Your Team on Secure Printing
Even the best technical security can be undermined by poor user habits.
Educate staff about printer security risks and your business’s printing policies. Include this in new employee inductions and regular security awareness training.
Establish clear guidelines for handling sensitive documents, including collecting printouts immediately and reporting any suspicious printer behaviour.
Create simple procedures for secure printing that staff will actually follow. Complicated processes often get ignored or bypassed.
Regular reminders help reinforce good habits: consider monthly security tips that include printer best practices.
What Hampshire Businesses Need to Know About Compliance
If your Hampshire business handles personal data, payment information, or works with government contracts, printer security isn’t just good practice: it’s often a legal requirement.
GDPR obligations extend to how you handle personal data during printing, including secure disposal and access controls.
Industry standards like ISO 27001 include specific requirements for securing all network-connected devices, including printers.
Client contracts increasingly include cybersecurity requirements that cover all aspects of data handling, not just computers.
The UK’s National Cyber Security Centre provides comprehensive guidance on printer security that Hampshire businesses should review and implement.
When to Replace vs. Secure Your Current Printers
Sometimes the most cost-effective approach is replacing outdated equipment rather than trying to secure devices that weren’t designed with security in mind.
Consider replacement if your printers are more than five years old, no longer receive firmware updates, or lack basic security features like user authentication.
Focus security efforts on newer devices that support modern security protocols and receive regular manufacturer updates.
Budget for regular updates. Plan printer replacements as part of your IT refresh cycle, typically every 3-5 years for business-critical devices.
