It features fast print speeds up to 6 inches per second, supporting resolutions of 203 dpi and 300 dpi for crisp labeling. The model integrates USB, Ethernet, and optional wireless connectivity to fit diverse network requirements. It supports multiple media types, including labels, tags, and wristbands, with easy media loading facilitated by a clamshell design. The printer is powered by a high-performance processor and memory to handle complex label formats efficiently. Zebra’s Link-OS environment offers enhanced remote management and firmware upgrade capabilities for optimal operation.

The ZD421 offers versatility with dual print technology (thermal transfer and direct thermal). It boasts user-friendly operations with an intuitive LCD interface and simple media loading. Robust connectivity options including USB, Ethernet, and Bluetooth improve flexibility. High printing speeds and resolution provide excellent print quality for diverse business applications. The modular design supports quick access to media and ribbons, minimizing downtime. Compatibility with Zebra’s suite of software enhances device management and integration.

One limitation is its relatively compact build, which may restrict larger media rolls, requiring frequent replacement in high-volume environments. While connectivity options are extensive, some advanced wireless features come only as optional add-ons. Its maximum print width is limited to 4.09 inches, which may not suit wide-format label needs. The device may require frequent ribbon changes in thermal transfer mode depending on print volume. Additionally, some users report the initial setup process could be complicated without technical knowledge. Firmware updates necessitate network or USB connection, which could pose challenges in isolated setups.
