How to Ensure the Privacy and Security of Network Printers: A Comprehensive Guide

When connecting a printer via Wi‑Fi or a wired network, make sure the connection is encrypted. If the connection is unsecured, data transmissions could be intercepted or tampered with.

Solution ：

• Ensure the printer is connected to an encrypted Wi‑Fi network. Use the WPA3 encryption protocol to enhance network security.
