Top 10 Tools for Network Printer Control in 2026

How to Securely Implement Network Printer Control in Your Office

Implementing secure network printer control reduces data leakage, prevents unauthorized use, and improves device management. Below is a practical, step-by-step guide IT teams can follow to secure printers across an office environment.

1. Inventory and baseline

  • Discover devices: Use network scanning tools (Nmap, Angry IP Scanner, or your RMM) to find all printers and multifunction devices (MFDs).
  • Record details: Capture make/model, IP/MAC address, firmware version, physical location, and admin credentials.
  • Baseline configuration: Note current settings for network protocols, services (e.g., IPP, LPD, SMB), and user access methods.

2. Network segmentation and access control

  • Isolate printers: Place printers on a dedicated VLAN or subnet to limit lateral movement and apply tailored firewall rules.
  • Restrict access: Allow only required hosts or subnets via ACLs; use port-based restrictions to limit protocols (e.g., only IPP/631, LPD/515 if needed).
  • Guest separation: Ensure guest Wi‑Fi networks cannot reach printer VLANs.

3. Strong authentication and admin controls

  • Change defaults: Immediately replace default admin passwords with unique, strong credentials stored in your password manager.
  • Role-based access: Where supported, enable role-based accounts with least privilege for users and technicians.
  • Centralized management: Use an MDM or printer management platform with secure authentication (SAML/AD integration) to administer devices.

4. Secure communication

  • Encrypt traffic: Enable TLS/HTTPS for web management interfaces, IPPS or IPP over TLS for printing, and SMB signing for Windows file printing.
  • Disable insecure protocols: Turn off Telnet, FTP, and any legacy print protocols (e.g., unsecured LPR/LPD) unless absolutely required.
  • Certificate management: Install manufacturer or internal CA-signed certificates; avoid self-signed certs on production devices.

5. Firmware and patch management

  • Regular updates: Establish a schedule to check and apply firmware updates from vendors.
  • Test before deploy: Apply updates first in a lab or limited group to verify compatibility.
  • Vulnerability monitoring: Subscribe to vendor advisories and CVE feeds for printer models in use.

6. Logging, monitoring, and alerting

  • Enable logs: Turn on audit logging for admin actions, print jobs, and network access.
  • Centralize logs: Forward logs to your SIEM or logging server for retention and correlation.
  • Alerting: Create alerts for suspicious activity—multiple failed admin logins, firmware tampering, or large-volume job spikes.

7. Secure print release and data protection

  • Pull printing: Implement secure print release (PIN, badge, or mobile auth) so jobs only print when the user is physically present.
  • Encrypt stored jobs: Ensure temporary storage on MFDs is encrypted and auto-wiped after jobs complete.
  • Disable local storage: Where possible, disable or clear hard drives in MFDs, or enable full-disk encryption.

8. User training and policies

  • Acceptable use policy: Publish rules for printing sensitive documents and enforce color/volume controls if needed.
  • Awareness training: Teach staff to verify printer names, use secure release, and report suspicious printer behavior.
  • Onboarding/offboarding: Include printer access provisioning and revocation in HR workflows.

9. Physical security

  • Secure placement: Place printers in monitored or locked areas when handling sensitive prints.
  • Restrict USB ports: Disable or lock USB and other local interfaces to prevent direct data extraction.

10. Incident response and recovery

  • Playbooks: Create procedures for compromised devices: isolate the VLAN, collect logs, reset device to factory, reimage if supported, and restore from known-good configs.
  • Backups: Keep configuration backups for rapid redeployment.
  • Post-incident review: Conduct root-cause analysis and update controls accordingly.

Quick checklist (priority actions)

  • Change default admin credentials.
  • Isolate printers on a dedicated VLAN.
  • Enable TLS for management and printing.
  • Implement secure print release.
  • Keep firmware up to date and enable logging.

Following these steps will materially reduce the risk posed by networked printers while improving manageability and compliance.
