Zebra ZD421
The ZD421 is a 4-inch desktop label printer from Zebra's ZD400 series, used for shipping and product labels, barcodes, wristbands and receipts in offices, retail back rooms and small warehouses. It is offered in direct thermal or thermal transfer versions, the latter with either a ribbon roll or a simple drop-in ribbon cartridge. Print resolution is 203 dpi with 300 dpi as an option, at up to 152 mm per second. Printing is driven by ZPL II and EPL, and setup runs from a free mobile app over Bluetooth Low Energy. Ethernet, dual-radio Wi-Fi with Bluetooth and a battery are available as options, and healthcare models with disinfectant-ready casings sit in the same family.
