Auto connect users using freeradius

[Muhammed Buvaydani]

Hello, I  am trying to configure freeradius to auto-authenticate or connect users. let's say I have mac address table which has a whitelist for mac address, how can I configure freeradius to connect these mac address automatically without a web page, I don't know how can I do that, actually I am working on hotspot system, I can connect users when they send request from a web page, but what about the devices which do not have web browser like (Printer), how can I do that.
