It supports a print width of up to 4.09 inches (104 mm) and a resolution of 203 dpi, balancing quality and speed. The printer operates on direct thermal and thermal transfer printing technologies, making it versatile for printing durable labels with ribbons or short-term labels without. Connectivity options include USB, Serial (RS-232), and parallel interfaces, allowing integration with various systems. The device features a media sensor that supports continuous, die-cut, black mark, and notch media types. This model includes an intuitive control panel and supports multiple barcode symbologies for label customization. Its robust design ensures reliable printing with a maximum print speed of up to 5 inches per second, suitable for small to medium volume applications.

The firmware supports EPL and ZPL programming languages, providing compatibility with legacy and newer software solutions. It is designed to reduce user downtime with easy ribbon loading and maintenance procedures. The GK420t is optimized for label applications including shipping, asset tracking, and product identification, enhancing office and warehouse productivity.

The Zebra GK420t offers several notable advantages. Its compact desktop design saves space while providing reliable printing performance. The dual printing technology supports both direct thermal and thermal transfer methods, enabling flexibility for different labeling needs. The 203 dpi resolution ensures clear, readable text and barcodes for professional labels. Multiple connectivity options make it easy to integrate into existing office setups. Its compatibility with EPL and ZPL enhances versatility across printing environments. Additionally, the printer’s simple ribbon loading reduces maintenance time, improving user efficiency.

Despite its advantages, the Zebra GK420t has limitations. The maximum print speed of 5 inches per second may be insufficient for high-volume industrial environments. It supports only up to 4.09-inch print width, which might be restrictive for wider label sizes. While it includes USB, serial, and parallel interfaces, it lacks modern network connectivity like Ethernet or Wi-Fi by default. The 203 dpi print resolution, although adequate for many labels, is not suitable for very high-detail graphics or fine text. The device's older model status may mean limited support and spare parts availability over time. Moreover, media compatibility is limited to specific label types, requiring appropriate supplies to function properly.
