In today’s digital workplace, information security is at the forefront of every organisation’s priorities. Businesses invest heavily in securing their networks, encrypting data, and training employees on cybersecurity best practices. However, one area often overlooked is the office printer.
Despite being essential to daily operations, printers and multifunction devices can present serious vulnerabilities if not properly managed. Unsecured print environments are responsible for a surprising number of data breaches each year, exposing confidential information and placing businesses at risk of non-compliance with UK data protection laws.
Managed Print Services (MPS) provide a structured, proactive approach to reducing these risks. By managing print infrastructure centrally, introducing access controls, and applying consistent security standards, MPS ensures that sensitive information remains protected throughout the document lifecycle.
This article explores the main security threats in unmanaged print environments and explains how Managed Print Services help to mitigate them.
The Overlooked Vulnerability: Printers as Network Devices
Modern printers are not just output machines; they are intelligent, network-connected devices capable of storing, transmitting, and processing data. This makes them part of an organisation’s wider IT infrastructure. When left unmanaged, printers can become weak points that hackers exploit to gain access to sensitive information or internal networks.
Unmanaged devices often run outdated firmware, lack encryption, or use default passwords that can be easily discovered. In addition, print jobs stored in device memory or left uncollected on output trays can contain confidential data such as financial records, employee information, or client contracts.
Without proper management, businesses risk exposing this data to both internal and external threats.
Common Security Risks in Unmanaged Printing
1. Unauthorised Access to Printed Documents
One of the simplest but most frequent risks occurs when printed documents are left unattended on a printer tray. Sensitive information can be viewed or taken by anyone passing by, whether intentionally or accidentally. This issue is especially problematic in shared office environments or public spaces where multiple users rely on the same device.
2. Unsecured Printer Memory and Storage
Many printers and multifunction devices retain copies of recent print, scan, or copy jobs in their internal memory. If this data is not encrypted or properly deleted, it can be retrieved later, even after the printer has been sold, recycled, or disposed of.
Data stored on printer hard drives can include sensitive financial details, personal data, and even confidential correspondence. In unmanaged environments, there is often no policy or system in place to wipe or secure this information.
3. Network Vulnerabilities and Hacking
Unmanaged printers are often connected to the corporate network without adequate firewalls or access restrictions. Hackers can use these devices as entry points to access other connected systems. In some cases, attackers exploit open printer ports to install malware or intercept print jobs.
Because many printers are left with factory-default passwords or outdated firmware, they provide an easy target for cybercriminals seeking to exploit overlooked devices.
4. Weak User Authentication
In traditional printing environments, anyone with access to the network can send a document to a printer. There is no control over who prints what, when, or where. This lack of authentication makes it impossible to prevent misuse or to trace the source of unauthorised prints.
5. Lack of Audit and Oversight
Without centralised monitoring, there is no visibility into who is printing or copying documents, what is being printed, or how often devices are used. This lack of oversight makes it difficult to detect suspicious activity, track data breaches, or enforce company printing policies.
6. Non-Compliance with Data Protection Regulations
Under the UK General Data Protection Regulation (GDPR), organisations are required to protect personal data from unauthorised access or disclosure. Failing to secure printed documents or digital copies stored on printers can constitute a compliance violation, leading to financial penalties and reputational damage.
An unmanaged print environment therefore not only increases the risk of data breaches but also puts a company’s legal compliance at stake.
How Managed Print Services Solve These Security Risks
Managed Print Services are designed to eliminate the weaknesses that arise in unmanaged printing environments. Through a combination of technology, policy, and proactive monitoring, MPS transforms the way organisations handle documents, ensuring that every stage of the process is secure.
Secure Print Release
With MPS, documents are not printed immediately upon being sent to the printer. Instead, they are held in a secure queue until the authorised user releases them at the device, usually by entering a PIN code or scanning an ID card.
This simple measure prevents sensitive information from being left unattended and ensures that only the intended recipient can collect the printout. It also reduces unnecessary printing, contributing to both security and sustainability.
User Authentication and Access Control
MPS introduces authentication systems that restrict access to printing, scanning, or copying functions based on user identity or role. Staff can be assigned specific permissions depending on their responsibilities, ensuring that confidential data is handled only by authorised personnel.
This control also provides an audit trail, allowing managers to track activity by user or department. If a security issue arises, it can be traced quickly and accurately.
Data Encryption and Secure Network Configuration
MPS providers Document Systems configure printers to use encrypted communication protocols, protecting data in transit between computers and devices. This prevents interception or tampering during the printing process.
Firmware updates and security patches are applied regularly to close vulnerabilities. Network configurations are reviewed to ensure that printers are properly segmented from critical systems, reducing the risk of external attacks.
Device Hard Drive Protection
Managed Print Services include measures to protect the internal storage of printers. Data is automatically encrypted, and devices are configured to overwrite or delete temporary files after each job.
When printers reach the end of their service life, MPS providers ensure that hard drives are securely wiped or destroyed in accordance with UK data security standards. This prevents sensitive information from being recovered from decommissioned devices.
Continuous Monitoring and Alerts
A key advantage of MPS is proactive monitoring. Devices are continuously observed for unusual activity, firmware issues, or unauthorised access attempts. Alerts are generated automatically, allowing potential threats to be identified and resolved before they lead to breaches.
This constant oversight provides a level of protection that is difficult to maintain with in-house management, where print security often receives limited attention.
Policy Enforcement and Audit Reporting
Managed Print Services make it possible to implement company-wide security policies consistently across all devices. Usage reports provide clear evidence of compliance and can be used to demonstrate adherence to data protection requirements during audits.
Managers can review reports to identify trends, such as excessive printing of confidential materials, and take corrective action to strengthen policy compliance.
Integration with Broader IT Security Strategies
Because modern printers are networked devices, MPS providers ensure that print security aligns with wider IT security frameworks. Features such as secure logins, data encryption, and controlled access integrate seamlessly with an organisation’s existing cybersecurity measures.
This integration closes a critical gap in data protection and creates a unified approach to information security across both digital and physical workflows.

Frequently Asked Questions (FAQs)
Is print security really a major concern for businesses?
Yes. Printers store and transmit data like any other networked device. If left unprotected, they can become entry points for cyberattacks or sources of data leakage.
Can MPS integrate with our existing IT security systems?
Absolutely. Managed Print Services are designed to align with your wider IT security strategy, integrating with authentication servers and encryption standards.
How does secure print release work?
Documents are held in a secure digital queue until the authorised user authenticates at the device. Only then is the job printed, preventing uncollected output.
What happens to sensitive data stored on printer hard drives?
MPS providers encrypt and regularly erase this data. When a device is retired, its storage is securely wiped or destroyed to prevent data recovery.
Does implementing MPS disrupt daily operations?
No. Providers plan implementation carefully to avoid disruption. Most changes are introduced gradually, and staff receive clear guidance on how to use the new secure printing features.
