A networked multifunction printer has a processor, an operating system, onboard storage, network interfaces, and in many cases an embedded web server. It accepts inbound connections, processes data, stores documents in memory, and communicates across the network. By any technical definition, it is an endpoint, and it carries the same categories of risk as any other endpoint you manage.
The distinction matters because the security controls applied to other endpoints, such as patch management, access control, encrypted communications, and activity logging, are rarely extended to printers. Firmware goes unpatched for years.
Default administrative credentials remain unchanged. Print jobs transit the network unencrypted. Output trays hold sensitive documents with no authentication requirement to retrieve them. Each of these conditions represents a concrete attack surface, not a theoretical one.
Network printer security is most often treated as the responsibility of whoever manages the printers physically, which in most organizations is facilities, office administration, or individual department heads rather than IT. That misalignment is where exposure accumulates.
Most printer security gaps fall into four categories. Each is addressable, but only if IT has visibility into the print environment in the first place.
Print jobs sent over the network without encryption can be intercepted in transit. In environments where sensitive documents are printed regularly, legal, financial, healthcare, HR — the exposure is proportional to the sensitivity of what’s being printed. TLS/SSL encryption for print data in transit is available on most modern devices but disabled by default on many and simply absent on older hardware still in active use.
Unprotected print queues expose job metadata and, in some configurations, job content to anyone with network access to the device. Spool files sitting on a print server represent a secondary exposure point that is easy to overlook during a standard vulnerability scan if printers are not included in the scan scope.
Printer firmware vulnerabilities are documented regularly by major vendors and tracked in CVE databases, but firmware update cycles for print devices lag far behind what most IT teams apply to other managed endpoints. Devices running firmware that is multiple versions behind the current release are carrying known, publicly documented vulnerabilities. Without a managed firmware update process, that exposure compounds quietly over time.
Factory-set administrative passwords and SNMP community strings are rarely changed at deployment and almost never rotated afterward. An attacker with network access and a list of default credentials for common printer models has a reliable path to administrative access on unmanaged devices, including the ability to exfiltrate stored documents, modify device configuration, and pivot to adjacent network segments.
Run through this list against your current fleet. Each item is a discrete control that can be verified and remediated independently.
If your fleet is not covered by a managed print program with built-in security controls, a print assessment from Print Image Solutions will show you exactly where your environment stands.
The structural challenge in printer security is not technical. It is organizational. In most businesses, IT owns network security but does not own the printers. Print devices are purchased by departments, managed by office administrators, and serviced by whoever responds to a repair call.
IT may have no visibility into the firmware version running on a given device, no record of whether default credentials were changed at deployment, and no process for including printers in routine vulnerability management.
That gap is not the result of poor security judgment. It is the predictable outcome of a procurement and management model that treats printers as office equipment rather than networked infrastructure. Closing it requires either extending IT’s scope to include formal management of every print device, or implementing a managed print services relationship that brings the print environment under structured oversight by design.
A well-structured managed print program addresses print security not as a feature add-on but as a baseline operating condition. Firmware updates are applied on a defined schedule rather than reactively. Device configurations are standardized at deployment and audited on an ongoing basis.
Secure print release is enabled across the fleet, ensuring that sensitive documents require authentication before printing. Print management software provides IT administrators with centralized visibility into device status, access logs, and usage activity across every connected device.
Decommissioned devices are wiped before disposal, closing the data exposure risk that most organizations only discover after the fact. For organizations in regulated industries, this documentation trail supports compliance requirements that a manual, decentralized fleet management approach cannot reliably produce. Our managed print services for healthcare clients, for example, operate under HIPAA obligations that make print security a compliance requirement rather than a best practice.
The practical result is a print environment that is managed with the same discipline applied to the rest of your endpoint infrastructure, without requiring IT to absorb the workload of managing every device directly. Our service and repair team handles firmware updates, proactive maintenance, and device-level security configuration as part of the standard managed service relationship.
Printer security is not a niche concern for high-security industries. It is a standard endpoint security issue that most organizations have not yet formalized because the print environment has historically sat outside the scope of IT’s managed infrastructure. That is changing as attackers increasingly target the paths of least resistance on corporate networks, and unmanaged printers represent exactly that.
The audit checklist above gives your team a starting point today. For organizations that want a complete picture of their current print security posture alongside a path to ongoing managed oversight, Print Image Solutions offers a complimentary 30-day print fleet assessment that covers device inventory, configuration review, and a full set of recommendations grounded in your actual environment.
