Product Features

Dual Printing Technologies

The Zebra GK420t supports both Thermal Transfer and Direct Thermal printing methods. Thermal transfer printing requires the use of a ribbon, providing durable, long-lasting prints. Direct Thermal printing, on the other hand, uses specially treated thermal paper and does not require a ribbon, making it ideal for short-term applications like shipping labels.

High-Speed Printing

With a maximum print speed of 5 inches per second, the Zebra GK420t can efficiently produce high-quality labels without compromising speed. This feature helps businesses keep up with demanding labeling tasks and improves overall workflow efficiency, especially in high-volume environments.

Flexible Connectivity Options

The GK420t offers multiple connectivity options, including USB, Serial, and Centronics Parallel ports. This flexibility ensures easy integration into a variety of systems and setups, making it compatible with both older and newer hardware.

Easy Integration with Zebra’s ZPLII Language

This printer supports Zebra Programming Language (ZPLII), the universal language of Zebra printers, which allows for easy integration into existing systems. The compatibility with ZPLII eliminates the need for additional software or complex configuration, streamlining the setup process and reducing potential for errors.

Durable, Low-Maintenance Design

The GK420t is designed for durability and frequent use, featuring a double-walled ABS case construction that provides resistance to wear and tear. The OpenACCESS™ design simplifies media loading, reducing downtime, while the head-up sensor ensures accurate printing alignment. Additionally, the printer features permanent downloading of label formats, soft fonts, and graphics, which enhances throughput and efficiency.

Energy Efficient

The Zebra GK420t is Energy Star approved, ensuring low power consumption while delivering high performance. This energy efficiency helps reduce operational costs, making it a sustainable choice for businesses aiming to minimize energy usage.
