The Zebra ZT231 is an industrial-grade thermal transfer label printer with a 4-inch print width and 300 dpi resolution, aimed at warehouses, manufacturing lines and retail back-of-house operations that print product, shipping or asset labels in volume. This configuration includes a cutter with a catch tray for automatically cutting and collecting individual labels rather than leaving a long unbroken strip, and comes with EU/UK power cords for regional use. Connectivity covers USB, serial, wired Ethernet, Bluetooth Low Energy and a USB host port (for connecting a scanner or keyboard directly to the printer) — the breadth of interfaces reflects its role as a workhorse label printer meant to slot into many different existing systems rather than one fixed setup.
