Zebra 170Xi4 (Discontinued) is a heavy-duty industrial label printer designed for wide-format, high-volume printing in extreme and continuous-duty environments. Known for its rugged metal construction, high print accuracy, and long-life components, it supports both thermal transfer and direct thermal printing. The 170Xi4 was widely used for pallet labels, chemical labeling, and manufacturing applications before being discontinued and replaced by newer Zebra industrial printer models.
