Brother HL-L2320D

D0 No Radio — No radio at all. It cannot phone home.

The unplug test

Nothing changes. USB in, paper out. No radio, no account, no app, and nothing that can reach a Brother server. Predates the era when a printer expected a relationship with its manufacturer.

Why this tier: Brother's own specification page lists Hi-Speed USB 2.0 as the sole interface and states the model lacks wireless and built-in Ethernet, while naming the wireless variants in the same series.
