A multifunction printer can hold more sensitive information than many businesses realize. It may receive payroll records, signed contracts, client files, medical forms, invoices, and employee documents every day. If that device is connected to your network without proper controls, it can become a quiet entry point for data exposure, ransomware, or unauthorized access. Learning how to secure office printers is not just an IT task. It is a practical way to protect client trust, maintain compliance, and keep daily operations moving.
Why Office Printers Are a Security Risk
Modern office printers are networked computers with scanners, storage, web interfaces, user accounts, and sometimes cloud connections. They process documents, retain print jobs, and communicate with workstations, email systems, and file-sharing platforms. Yet they are often installed, given a Wi-Fi password, and forgotten until they jam or run out of toner.
That gap creates risk. An attacker may use an unpatched printer as a path into the network. A visitor or former employee may print confidential records without authorization. Documents left in an output tray can be viewed by anyone walking through the office. A retired printer with an unencrypted hard drive may still contain years of stored scans and print jobs.
The right level of protection depends on the business. A small office with one printer has different needs than a law firm, medical practice, warehouse, or multi-site retail operation. Still, every organization should treat printers as managed network endpoints rather than simple appliances.
How to Secure Office Printers at the Network Level
Start by identifying every printer, copier, scanner, and multifunction device connected to your business. Include equipment on Ethernet, Wi-Fi, guest networks, and remote locations. If no one can say who owns a device, what it stores, or when its firmware was last updated, that is a security gap worth closing.
Printers should not sit on the same unrestricted network as servers, workstations, point-of-sale systems, cameras, and guest devices. Network segmentation places printers on a separate network segment or VLAN and allows only the traffic they actually need. For example, authorized employee computers may be allowed to send print jobs, while the printer has no reason to communicate freely with every device in the office.
This approach limits damage if a printer is compromised. It also makes troubleshooting easier because printer traffic is clearly separated from business-critical systems. Segmentation requires proper firewall rules and network planning, so it is a good place to involve an IT provider rather than relying on default settings.
Wi-Fi printers deserve extra attention. Avoid connecting business printers to an open or shared guest network. Use strong wireless encryption, remove outdated Wi-Fi protocols where possible, and change default wireless credentials. If a printer does not need Wi-Fi, a wired connection is often easier to control and more reliable in a busy office.
Change Defaults Before the Printer Goes Live
Default administrator usernames and passwords are widely known. Leaving them in place allows anyone on the network, and sometimes anyone who reaches the device’s web interface, to change settings, view address books, reroute scans, or disable security features.
Assign a unique administrator password to every printer and store it securely in your business password manager. Limit administrative access to the people responsible for IT support. Staff who only need to print should not have the ability to alter network, email, or security settings.
Also review the printer’s built-in services. Many devices enable features that are not necessary for a particular office, such as remote administration, fax forwarding, cloud printing, Bluetooth, FTP, or legacy file-sharing protocols. Disable what you do not use. Each enabled service is another possible point of entry and another setting to monitor.
Keep Firmware and Print Software Current
Printer firmware updates are not optional maintenance. Manufacturers release firmware to correct security flaws, improve encryption, and address reliability problems. Delaying those updates may leave a known weakness in place long after a fix is available.
The challenge is that firmware updates can affect existing configurations or require a brief interruption. For a small office, updates can often be scheduled after hours. For a larger operation with a high-volume copier, shipping station, or point-of-sale printer, test updates first or schedule them during a low-impact window. Security should not create avoidable downtime.
Your print drivers and print management software also need attention. Use current, manufacturer-supported drivers and remove outdated drivers from workstations and print servers. Old drivers can create compatibility issues, open security concerns, and give employees multiple confusing printer options that are no longer valid.
A managed endpoint program can track printer-related software and firmware alongside computers, firewalls, and other network equipment. The benefit is consistency: patches are planned, documented, and checked instead of being handled only after a problem appears.
Control Who Can Print, Scan, and Release Documents
Printer security is also physical security. A secure network does not help if confidential documents remain in an open tray for 20 minutes.
For offices handling sensitive information, use secure print release. Employees send the job to the printer, then authenticate at the device with a PIN, badge, mobile credential, or approved account before the document prints. This reduces abandoned paperwork and helps prevent someone from accidentally collecting another employee’s documents.
User authentication can also limit access to scanning functions. A receptionist may need to scan paperwork to a designated folder, while accounting staff may need access to invoice workflows and leadership may need secure email scanning. Set permissions based on job roles, not convenience. That takes more initial setup, but it reduces the chance that data is sent to the wrong destination.
Review address books stored on multifunction printers as well. Old employee email addresses, personal contacts, and outdated file-share locations should be removed. If a device can scan directly to email, use a dedicated, secured service account where appropriate rather than an individual’s mailbox credentials.
Protect Data Stored Inside the Device
Many multifunction printers retain documents on internal storage, either temporarily or for longer periods. This can include scanned files, queued jobs, copies, and system logs. Before deploying a device, verify whether its storage is encrypted and whether stored jobs are automatically overwritten after completion.
Encryption protects data if the device is stolen or serviced. Automatic job deletion reduces the amount of information sitting on the device in the first place. Both matter, particularly for businesses subject to contractual confidentiality obligations or compliance requirements such as HIPAA.
When a printer is moved, returned to a leasing company, sent for repair, or disposed of, treat its storage like a computer hard drive. Resetting a device is not always enough. Confirm that internal storage has been securely wiped, removed, or destroyed according to the device type and your retention policies. Request documentation from vendors when they handle the process.
Build Printer Security Into Daily Operations
The strongest controls fail when no one knows they exist. Employees should understand that sensitive documents must be collected promptly, unknown USB drives should not be inserted into printers, and printer error messages should be reported rather than ignored. A short reminder during onboarding is often enough to prevent common mistakes.
Your office should also have clear ownership for printer issues. Someone needs to know who can approve configuration changes, respond to a suspected breach, and contact support when a device behaves unexpectedly. Warning signs include unexplained print jobs, new administrator accounts, changes to scan destinations, repeated network disconnects, or devices appearing on the network that were never authorized.
Logging helps turn those warning signs into usable evidence. Where supported, send printer logs to a centralized monitoring system or review them as part of regular IT health checks. This may be more than a one-person home office needs, but it is a sensible control for firms handling client records, payment data, or regulated information.
For Las Vegas businesses without an internal IT department, printer security often gets missed because it falls between the copier vendor, internet provider, and general computer support. One trusted technology partner can establish ownership across the device, network, endpoints, monitoring, and incident response. System Integrators of Nevada helps businesses close those gaps without forcing owners to become printer-security experts.
A secure printer should be nearly invisible to employees: authorized documents print when needed, confidential pages do not sit exposed, and the device does not create an unmonitored path into the network. Put the controls in place before an incident turns an ordinary office printer into a business interruption.
