When businesses think about cybersecurity, the conversation usually starts with firewalls, antivirus software, and email filtering. Printers almost never come up — and that is exactly the problem.

In 2026, every networked printer and multifunction device (MFP) in your office is a live endpoint on your business network. It has its own operating system, its own storage, and its own open ports. If it is not actively managed — patched, monitored, and configured — it is a gap in your security posture. This guide explains what that means, what it costs when ignored, and what Colorado businesses can do about it right now.

Why Printers Are Now a Primary IT Risk

The modern office printer is not the device it was ten years ago. Today’s MFPs scan to cloud, integrate with Microsoft 365, store document history internally, serve a built-in web admin interface, and connect to your network around the clock. That capability is also a threat surface.

This gap is not theoretical. According to Quocirca’s print security research, 68% of organizations have experienced data loss connected to unsecured printing. The attack path is well-documented: exploited admin panel, unpatched firmware vulnerability, or intercepted print job in transit. None of these require sophisticated tooling — they require an unmanaged device and an attacker who knows where to look.

The Top Printer Security Threats in 2026

These are the vulnerabilities ABT’s managed IT team sees most often when assessing Colorado business networks. None of them require an exotic attack — they are the result of standard printer deployments with no active management.

1. Unsecured Admin Panels

Every modern printer has a built-in web interface for remote configuration. If it is running on HTTP instead of HTTPS, or still using the factory default password, anyone on your network — or sometimes anyone on the internet — can access it. From there, an attacker can read stored print jobs, change network configuration, or use the printer as a pivot point to reach other systems.

2. Unpatched Firmware

Printer firmware vulnerabilities are disclosed regularly by manufacturers — Canon, HP, Kyocera, Xerox all publish security bulletins. The problem is that firmware patches are rarely applied unless someone is actively managing the fleet. A device installed in 2022 running its original firmware in 2026 may have a dozen known, documented vulnerabilities that have never been addressed.

3. Data Residue in Device Storage

Print jobs, scanned documents, and faxes are often written to the printer’s internal storage and not automatically cleared. When a device is resold, returned at lease end, or disposed of without a proper wipe, that data travels with it. For businesses handling patient records, financial data, or legal documents, this is a compliance event waiting to happen.

4. Cloud Print Misconfiguration

Cloud print integrations — including Microsoft Universal Print, Google Cloud Print successors, and vendor-specific platforms — are increasingly common in hybrid environments. If access controls are misconfigured or API credentials are weak, print jobs sent through these pipelines can be intercepted or routed incorrectly.

5. Open Ports Running Unused Protocols

Out of the box, most printers enable FTP, Telnet, and SNMP by default. These protocols are legacy, largely insecure, and almost never needed in a modern office environment — but they remain active because no one turned them off at installation. Each one is a documented attack surface.

6. Unattended Output Trays

Still the most basic exposure: sensitive documents — payroll, contracts, patient records, HR files — printed to a shared tray and left uncollected. No sophisticated attack required. This is an insider threat and a compliance risk that secure print release (pull printing) eliminates entirely.

Searching for Printer Repair? It May Not Be a Hardware Problem

Many of the printer service calls ABT receives across Denver, Colorado Springs, and Westminster turn out not to be hardware failures at all. The device “isn’t working” — but the actual cause is a firmware conflict, a network configuration change, an expired certificate, or a security policy that locked down a port the printer needed.

If your printer is showing any of these symptoms, the root cause is more likely a management or security issue than a mechanical one:

If you need copier or printer repair in Colorado, ABT provides that service — but more often, what businesses actually need is a managed relationship that keeps the device configured correctly in the first place. The distinction matters because one approach fixes the symptom and the other eliminates the cause.

Printer Security Hardening Checklist for 2026

Work through this list for every networked printer and MFP in your environment. If you are managing more than five devices, or if your team does not have dedicated IT resources, these steps should be handled by your managed IT provider or managed print services partner as part of ongoing fleet management.

Choosing Hardware Built for Security

Not all printers are built the same way from a security standpoint. When your next lease comes up or you are adding devices, the security capabilities of the hardware itself matter as much as the price per page. ABT is an authorized dealer for the manufacturers that lead on this:

Security features vary by model and configuration. When evaluating a new device, ask the vendor specifically: what firmware management process is included in the service agreement, and how does the device handle data at rest and end-of-life? ABT configures every device to security standards at deployment — not left at factory defaults.

Why Managed Services Close the Gap That Hardware Alone Cannot

Even the most security-capable printer on the market is only as secure as the process managing it. Firmware does not patch itself. Logs do not review themselves. Access controls drift over time as staff change and configurations age. This is the problem that Managed Print Services and Managed IT Services solve — not by replacing security features, but by ensuring they are actually active and maintained.

The two services are designed to work together. ABT is one of the few Colorado providers that delivers both from the same team — which means your print environment and your broader IT security posture are managed as a unified system, not as separate vendor relationships that never talk to each other.

Physical Security Belongs in the Same Conversation

Print security is part of a broader physical and digital security posture. A printer in an unsecured hallway, a copy room with no access control, or a shared MFP accessible to visitors undermines every software-level control you put in place. If sensitive documents can be physically retrieved from a print tray by anyone who walks in — the firmware patches do not matter.

ABT’s cloud-managed access control systems — including Verkada and Avigilon — integrate with print environments to create credential-based access to device areas and document rooms. The same badge that releases a secure print job can control who enters the room where the device lives. That is a complete security layer that most businesses do not have and most competitors cannot deliver from a single provider.
