Zebra QLn320-HC (Discontinued) is the healthcare-grade version of the QLn320, built specifically for clinical environments. It features a disinfectant-ready, medical-grade housing that withstands frequent cleaning while delivering the same reliable direct thermal printing performance. The QLn320-HC was widely used in hospitals and laboratories for specimen labeling, patient identification, and medication labeling before being discontinued in favor of newer Zebra healthcare mobile printers.
