Each Deco M4 has two Gigabit Ethernet connections. This means that a network printer can be set up directly via Ethernet. But WLAN printers can also be used with it, because the printer simply receives an IP address from the M4 Mesh System via which a printer can be addressed either in the WLAN or LAN.

Works perfectly for me: Connect WiFi-capable printers with WLAN (mesh) and control them as usual from the application.
