Zebra 110PAX4 (Discontinued) is an industrial print engine designed for high-speed, high-volume label printing in automated print-and-apply systems. Built for continuous-duty operation, it features a rugged metal construction, precise print registration, and supports both thermal transfer and direct thermal printing. The 110PAX4 was widely used in manufacturing, logistics, and packaging lines before being discontinued and replaced by newer Zebra print engine solutions.
