A print server is a system that manages print jobs and shared printer access for users and devices on a network. It queues jobs, applies printer settings and publishes printers to clients, so it becomes a control point for access, logging and driver distribution.
What a Print Server Actually Does
A print server is more than a convenience layer between users and printers. It brokers queued work, exposes shared queues, applies printer defaults, and often becomes the place where driver packages, printer objects, and access policy are centralized.
Because that role sits on the path between endpoints and devices, the print server can shape who gets access, which settings are trusted, and what client software is deployed. In many environments it is also the administrative control plane for printer discovery and lifecycle management.
Why Print Servers Matter in Enterprise Security
Print servers matter because they aggregate trust. A single server may service many departments, distribute drivers to many endpoints, and hold the settings that determine how print infrastructure behaves across the network. If that server is weakly governed, the impact extends beyond printing into endpoint stability and access control.
They also tend to inherit broad reach by design. Printer publication, queue permissions, and automated driver delivery can create an easy path from a low-sensitivity office service into a much wider operational footprint if the server is not hardened and monitored.
Common Security and Operational Dependencies
The security of a print server is tightly linked to the operating system it runs on, the printer drivers it publishes, and the service accounts or credentials used to reach multifunction devices and related services. That is why hardening the host and reducing unnecessary print roles are part of the security story, not separate concerns.
Print infrastructure also depends on reliable inventory and segmentation. If printers are treated as unmanaged peripherals, the server can become a blind spot for stale queues, orphaned drivers, excessive publishing, and inconsistent access paths.
For a practical hardening reference, see the Printer and Print Server Security Guide, which covers spooler hardening, Point and Print, and printer-related credential handling.
Where Print Server Risk Comes From
Risk usually comes from three places: privilege, exposure, and persistence. A print server often has enough trust to distribute software, enough connectivity to reach many clients, and enough administrative convenience that old queues, drivers, or credentials linger longer than they should.
When that combination is abused, an attacker may use the print path to deliver unwanted code, reach other systems, or harvest configuration and authentication material stored for printer workflows. The result can be wider than a simple print outage.
Risk and Threat Considerations
Print servers can become attractive targets because they sit at a privileged intersection of users, devices, and software delivery. A weakness in driver handling, print service configuration, or printer-access governance can turn a routine office service into a route for lateral movement, credential exposure, or broad operational disruption.
Failure mechanism: Untrusted or overly permissive print infrastructure can allow malicious driver delivery, service abuse, or reuse of stored printer credentials and settings, especially when the server is exposed beyond what the business actually needs.
Impact: Compromise can affect many endpoints at once, disrupt printing across the organisation, and expose adjacent systems through the trust relationships that the print server manages.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 addresses the attack surface, NIST SP 800-53 Rev 5 and CIS Controls v8 set the technical controls, and ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-53 Rev 5 | AC-3 — Access Enforcement | Print servers enforce who can submit, manage, or publish print queues. |
| IA-5 — Authenticator Management | Print workflows often depend on stored printer and service credentials that need lifecycle control. | |
| Recommendation — Enforce queue-level permissions so only approved users and admins can publish or submit print jobs. Rotate and protect printer-related credentials, keys, and service secrets on a defined lifecycle. | ||
| CIS Controls v8 | CIS-5 — Account Management | Print servers commonly rely on service accounts and shared administrative access paths. |
| Recommendation — Inventory and review print-server and printer-service accounts to remove stale or excessive access. | ||
| ISO/IEC 27001:2022 | A.8.20 — Network security | Print servers are networked systems that need controlled exposure and segmentation. |
| Recommendation — Segment print servers and limit network reachability to the clients and admins that need them. | ||
| OWASP Non-Human Identity Top 10 | NHI-05 — Overprivileged NHI | Printer service accounts and device credentials can become overprivileged non-human access paths. |
| Recommendation — Reduce privileges on printer and print-server service identities to the minimum required. | ||
Practitioner Guidance
Governance implication: Treat the print server as a shared infrastructure service with explicit ownership, not as an incidental support box. Its queues, drivers, and printer-publishing rules should be reviewed as part of the broader server and endpoint security baseline.
What to watch for: Excessive printer publication, unexpected driver changes, dormant queues, and printer-related credentials or service accounts that are broader than the workflow requires. Where print services are embedded in larger endpoint or server programmes, the Windows Server Hardening Guide is a useful companion for reducing host-level exposure, while the Enterprise IoT Security Programme Guide helps when printers are managed as part of a broader device estate.
