Key Advantages

The ZD421 offers a fast print speed of up to 6 ips, enhancing productivity for medium volume printing.

Its versatility in connectivity options including USB, Ethernet, Wi-Fi, and Bluetooth allows seamless integration in various environments.

Easy media loading with ribbon cartridge reduces downtime and simplifies maintenance.

Compatibility with Zebra’s Link-OS offers powerful remote management and device monitoring capabilities.

Compact and sleek design fits well in desktop or counter spaces without sacrificing performance.

High print resolution option (300 dpi) delivers crisp text and graphics for professional label printing.

Limitations

The ZD421 is designed primarily for medium-duty applications, so it may not meet extremely high-volume industrial printing needs.

Its maximum media width limits label sizes to 4.25 inches, restricting usage for wider label formats.

Some connectivity options, such as Wi-Fi and Ethernet, are available only as optional upgrades, which may increase overall cost.

It does not have the robustness or durability features required for harsh industrial environments.

The standard models come with a 203 dpi print head; upgrading to 300 dpi is optional and may add to cost.

No auto-cutter or peel-off options standardly included; may require additional accessories for such functions.
