Product features

  • Get years of printing performance
    The ZD421 is designed to handle advancing technology. Featuring an innovative architecture, it's engineered to power future printing. In comparison, it's 30% more powerful than the ZD420 Series and 700% more than the GK Series. This lets you run more tasks, perform more operations simultaneously, maintain security and be ready for what's next.
  • Backwards compatible with virtually any existing printer
    Deploy your ZD421 into your existing printer fleet with confidence. Use the same label formats and applications you're using today. It supports both EPL and ZPL printer languages, and can emulate languages normally associated with other printer brands using Zebra's Print DNA tool, Virtual Devices.
  • Connect it your way
    Integrate your ZD421 onto your existing wired and wireless networks, or connect it directly to any PC. Every ZD421 comes standard with USB and USB Host, and offers optional Ethernet, Serial and dual wireless radio with fast 802.11ac Wi-Fi and Bluetooth 4.1. Print from any Windows, Android or iOS device. Get your ZD421 up and running with Zebra's printer setup mobile app using Bluetooth Low Energy (BLE). Use the included Print Touch tag (NFC) to simply tap to pair and print.
  • Operate with ease and see status at-a-glance
    Take the guesswork out of printer status with the ZD421's five LED icons to instantly see what's needed to keep your printers up and running, from replenishing media to resolving printer issues. The advanced three-button user interface replaces the typical single-button/single-light interface common in desktop printers to offer added functionality and control. And, color-coded touch points guide you through media-handling tasks for speedy media changes.
  • Groundbreaking cartridge for instant ribbon changes
    The ZD421 is the only thermal printer to offer a ribbon cartridge that takes just a few seconds to load with fool-proof, one-way, first-time and every-time instant loading. The smart chip in the ribbon lets you know when the ribbon needs replacing.
  • Turn your ZD421 into a portable printer
    Easily transport your ZD421 printer on a cart or with Zebra's optional carrying case, using the battery option. Print on the spot to reduce steps and increase productivity. Power through a full shift with the high-capacity battery.
  • Movable sensor for comprehensive media compatibility
    The ZD421's movable media sensor lets you use virtually any media for greater flexibility across a variety of use cases.
