The Brother HL-L2400D is the cleanest choice for people who do not need network printing.
It is a USB-connected monochrome laser printer with automatic duplex printing and up to 32 ppm output. No Wi-Fi, no Ethernet, and no cloud path are required for normal local printing. For sensitive home-office printing, USB-only is a privacy advantage, not a limitation.
Use this when the goal is to keep the printer dumb, local, and physically connected to one computer.
