Zebra ZQ511 (3-Inch) & ZQ521 (4-Inch) Ultra-Rugged Mobile Receipt & Label Printers (203 DPI, IP54)

Engineered to deliver extreme military-grade durability and uncompromising wireless performance in the harshest field and industrial environments, the Zebra ZQ511 (3-Inch) and ZQ521 (4-Inch) Ultra-Rugged Mobile Receipt and Label Printers represent Zebra’s toughest on-the-move printing solutions for field service, direct store delivery (DSD), and warehouse logistics.

Designed and certified to exceed MIL-STD-810G military standards for shock, vibration, and temperature extremes, the ZQ511 and ZQ521 feature an exceptional IP54 rating (IP65 with optional exoskeleton) and survive repeated 6.6 ft / 2.0 m drops to concrete. Operating at 203 DPI with print speeds up to 5 inches per second (127 mm/s), both models incorporate Zebra’s Power Smart Print Technology to maximize battery endurance during continuous mobile shifts. Supporting both receipts and die-cut barcode labels (with optional linerless media handling to reduce environmental waste), advanced Bluetooth 4.1 Classic & Low Energy, and 802.11ac Wi-Fi with fast roaming, the ZQ500 Series guarantees all-day reliability in field logistics, utility citations, and route delivery.
