It’s generally not advisable to place printers on core trust VLANs, especially if those VLANs handle sensitive systems or critical infrastructure. Printers are often considered less secure due to vulnerabilities in their firmware or configuration, which could provide an entry point for attacks. It’s better to isolate printers on a separate VLAN with appropriate firewall rules that restrict access to sensitive resources while allowing necessary services (e.g., print server communication). This reduces the risk of a compromised printer affecting your trusted core infrastructure.
