Print Security: 5 Threats That Many Belgian SMEs Ignore

Print Security: 5 Threats That Many Belgian SMEs Ignore

Most Belgian SMEs consider their photocopier a simple office appliance. However, modern printing machines are in reality full-fledged computers connected to the corporate network and capable of storing, processing, and transmitting sensitive data. This misconception exposes thousands of organizations to major cybersecurity risks.

This article explores 5 often-forgotten print threats by Belgian IT decision-makers and shows you how to eliminate them without compromising your productivity.

1. The Internal Hard Drive: The Forgotten Ticking Time Bomb

Did you know that most professional photocopiers are equipped with an internal hard drive? This component automatically stores every document copied, scanned, or printed — including sensitive confidential data.

The Concrete Risk

Imagine this scenario: a medical imaging lab prints 100 X-ray images for testing. An inexperienced technician performs maintenance and retrieves the hard drive. He only needs 5 minutes to access unencrypted images using free tools.

In Belgium, where health data is governed by GDPR and data protection law, this breach is a regulatory catastrophe: fines up to 4% of annual revenue, loss of customer trust, and reputational damage.

How to Protect Yourself

  • Hard Drive Encryption: Require that your leased photocopier includes native AES-256 encryption
  • Secure Configuration: Configure automatic data erasure after each task
  • Maintenance Contracts: Include a clause prohibiting unauthorized access to components
  • Annual Audit: Request a certification of secure data destruction at the end of the lease

Our Recommendation: When signing a photocopier lease in Belgium, demand a technical data sheet specifying the data destruction protocol applied at the end of the contract. This is your legal guarantee.

2. Unencrypted Network Printing: The Invisible Interceptions

Photocopiers connect to your corporate network via Ethernet or WiFi. Very few organizations configure print stream encryption — meaning your documents travel in plain text across the network.

The Invisible Attack

An attacker on your WiFi network (or on a compromised network segment) can:

  • Intercept print jobs before they reach the machine
  • Read in plain text every printed page (contracts, invoices, payroll slips, etc.)
  • Modify jobs in transit (inject content, change parameters)
  • Collect IP addresses of users who print

How to Protect Yourself

  • HTTPS and Secure IPP: Ensure your network infrastructure supports IPP-over-HTTPS
  • Segmented Network: Isolate your printer fleet on a dedicated VLAN with no internet access
  • Network Authentication: Configure 802.1X if supported by your machines
  • Perimeter Firewall: Block all unauthorized flows to/from printing machines

For Belgian SMEs using leasing: Require that the provider documents the secure network encryption configuration at signature and includes this in the maintenance contract.

3. Outdated Drivers: The Unlocked Doors

Modern photocopiers run proprietary operating systems (often based on Linux or Windows) and require client drivers on workstations.

The problem? The majority of Belgian SMEs never update these drivers.

Why This Is a Danger

Manufacturers (Ricoh, Canon, Xerox, etc.) regularly publish security patches for their drivers. An unpatched vulnerability in a print driver can enable:

  • Remote code execution on the printing machine
  • Theft of authentication certificates stored in the driver
  • Administrator access to the machine’s management interface

In February 2024, a critical vulnerability in Xerox drivers was exploited by attackers in Belgium to infiltrate a mutual insurance company in Brussels.

How to Protect Yourself

  • Automated Patch Plan: Configure automatic driver updates
  • Annual Audit: Verify driver versions across all workstations (minimum acceptable = N-1)
  • Maintenance Included: Ensure your lease contract includes firmware updates at no extra cost
  • Vulnerability Registry: Follow CVEs (Common Vulnerabilities and Exposures) from your manufacturer

4. Default Access Credentials: The Forgotten Passwords

Every professional photocopier is equipped with a web management interface. This interface allows you to:

  • Configure network settings
  • View print histories
  • Download security logs
  • Modify access credentials

In 7 out of 10 cases, the default password has never been changed.

The Realistic Scenario

A malicious employee attempts to access the photocopier interface from another computer on the network. He tries the most common default codes:

  • admin / admin
  • admin / [empty]
  • ricoh / ricoh (Ricoh Aficio)

He gains access to the management panel in less than 30 seconds, then:

  • Views the complete scan history of all scanned documents
  • Extracts network authentication credentials (LDAP, Active Directory)
  • Configures the machine to send a copy of every scan to his email address

How to Protect Yourself

  • Immediate Change: Change the administrator password on all photocopiers immediately
  • Strong Password: Use a 12+ character password (uppercase, numbers, symbols)
  • Network Authentication: Restrict management panel access to internal IP range only
  • Quarterly Audit: Request access logs to the management panel
  • Team Training: Ensure the person responsible for maintenance understands best practices

5. Metadata Leakage: The Invisible Traces

Every print job generates metadata: who printed, when, how many pages, document title, source IP address, etc.

This metadata is stored in:

  • The photocopier log (hard drive)
  • The print server (CUPS server, Windows Print Server, etc.)
  • Client drivers

A system administrator — or an attacker with network access — can analyze this metadata to reconstruct your company’s document activity without ever seeing the actual documents.

Possible Exploitation

Print metadata leakage can reveal:

  • Employees’ actual working hours (productivity)
  • Organizational stress levels (increased printing before meetings)
  • Confidential projects (volume of secret documents)
  • Internal tensions (communication patterns by group)

A competitor would need only 2 months of metadata to anticipate your product launches.

How to Protect Yourself

  • Log Rotation: Configure automatic deletion of print logs after 30 days
  • Anonymization: Require that usernames are hashed in logs (not plain text)
  • Access Control: Limit log access to 2-3 people maximum
  • Compliance Audit: Verify quarterly that unnecessary logs are properly deleted
  • Log Encryption: Request log file encryption if your contract permits

Here’s a quick checklist for immediate use:

✅ Hard Drive:

  • Verify AES-256 encryption is enabled on all photocopiers
  • Request data destruction documentation from provider
  • Document contract expiration dates

✅ Network:

  • Isolate printer fleet on dedicated VLAN
  • Verify print streams use HTTPS/secure IPP
  • Block all unauthorized outbound access from machines

✅ Software:

  • Update all client drivers (minimum version = N-1)
  • Request patch roadmap from provider
  • Document firmware version of each machine

✅ Access:

  • Change default administrator password (immediately)
  • Restrict management panel access to IP range only
  • Document who has access to what

✅ Logs:

  • Verify log retention duration
  • Request username anonymization
  • Plan quarterly review

Integrating Print Security Into Your IT Strategy

For SMEs Without Dedicated IT

If your IT team is limited or non-existent, outsource print security management to your provider. Require in the contract:

  1. A signed secure configuration document
  2. An annual security review (free audit)
  3. A liability clause in case of breaches due to misconfiguration

For Organizations With Dedicated IT

Integrate print security into your overall IT security policy:

  • Appoint a print fleet manager
  • Schedule quarterly audits
  • Document all configurations and changes
  • Implement incident recovery (express replacement if compromised)

GDPR and Belgian Regulatory Compliance

Belgium strictly enforces GDPR. Your photocopiers process personal data (authentication email addresses, employee activity logs, scanned documents containing contact information).

Legal Responsibilities:

  • Maintain a processing register (including printer fleet)
  • Document data security (encryption, access, destruction)
  • Notify your Data Protection Officer of any incidents
  • Be able to prove compliance in case of regulatory inspection

Conclusion: Printing Is Not a Detail

Too many Belgian SMEs treat print security as a minor IT afterthought. This is a serious mistake.

Your photocopiers are critical access points to your network infrastructure and most sensitive data. A single breach could cost tens of thousands of euros in GDPR fines, not to mention reputational damage.

Act Now:

  1. Audit your current machines against the checklist above
  2. Update your lease contracts to include security clauses
  3. Train your team on best practices
  4. Plan an annual review with your provider

The 5 threats described in this article are not theoretical. They have already affected Belgian SMEs. Don’t be the next victim.
