The Zebra ZT610 is an industrial thermal transfer label printer, a step up from the ZT510 line, aimed at higher-volume warehouse, manufacturing and logistics labelling. This configuration prints at 203dpi across a 4-inch width, with tear-off dispensing, and includes a USB host port (letting external devices like a keyboard or scanner plug directly into the printer) in addition to Serial, USB and Gigabit Ethernet connectivity, plus Bluetooth 4.0 for wireless pairing. It supports Zebra's ZPL printer language for label design and integration with warehouse management software. The catalog lists it as 'Color', though the ZT610 is fundamentally a monochrome thermal-transfer print engine — this most likely refers to a ribbon or accessory colour-coding option rather than actual colour printing, and is worth confirming with the supplier before ordering if colour output is a requirement.
