A modern printer is a networked computer with storage, memory, and internet access — and that makes it a genuine security consideration, especially in an office.
This guide outlines the practical measures that keep your documents and network safe without specialist knowledge.
Why printers are a security risk
Printers can store copies of documents, hold network credentials, and act as an entry point to your wider network if left unprotected. Sensitive pages left in an output tray are a simple but common exposure.
Essential protective measures
- Change default administrator passwords immediately.
- Enable secure release so jobs print only when you authenticate.
- Keep firmware updated to patch known vulnerabilities.
- Use encrypted connections for print jobs where supported.
Managing access
Restrict who can print, scan, and change settings, and disable features and protocols you do not use. On shared networks, isolate the printer where possible so a single device cannot compromise everything else.
Protecting stored data
Printers with internal storage should encrypt it and securely erase data when devices are retired or returned at the end of a lease. Clearing stored jobs regularly reduces the amount of sensitive data at rest.
Firmware, Software & Security Updates
Keeping printer firmware current is one of the most important — and most overlooked — security measures. Firmware updates patch known vulnerabilities, close back-door access points, and add improvements to encrypted communication. Most modern printers can check for and apply updates automatically when connected to the internet.
Printer driver updates on client computers should also be managed, as outdated drivers can introduce compatibility gaps. For HP printers, the HP Smart app handles firmware updates automatically and notifies you when critical security patches are available. Always apply firmware updates promptly, particularly on networked business printers that handle sensitive documents.
