Quick view

The Zebra GC420T is a thermal transfer desktop printer designed for low to mid-volume labeling applications. It features a direct thermal and thermal transfer printing method, allowing versatile media usage including labels, tags, and receipts. The printer supports print widths up to 4.09 inches at 203 dpi resolution, providing clear and sharp barcode and text printing. It incorporates a 32-bit RISC processor with 8 MB DRAM and 4 MB Flash memory for rapid data processing and font storage. The GC420T connects via USB and serial interfaces, offering compatibility with various host systems. It is compatible with EPL and ZPL printer languages, enabling integration with Zebra's extensive software and label formats.

The compact design includes a clamshell-style case for easy media loading and a LCD display with operator controls for efficient operation. The printer supports linerless media and various ribbon formulations to enhance durability and print quality based on application needs. Its print speed reaches up to 4 inches per second, balancing productivity with cost-efficiency. Power is supplied by an external AC adapter specified for the model, included with the printer and tailored to ensure optimal performance.

The Zebra GC420T offers exceptional reliability for small to medium batch printing tasks with minimal maintenance. Its dual printing capabilities (thermal transfer and direct thermal) provide flexibility for various label types and longevity requirements. The inclusion of EPL and ZPL language support allows seamless integration into existing Zebra printer environments and easy replacement of older models. It features an easy-to-use clamshell design for quick media changes that reduce downtime. The compact footprint fits comfortably in most office or industrial workspaces, optimizing space utilization. Additionally, the printer supports multiple connectivity options enhancing adaptability within different network setups.

The maximum print resolution of 203 dpi may not be suitable for applications requiring very high detail or small font printing. Its print speed, while adequate for most office environments, may not fulfill high-volume industrial needs. The memory capacity is limited relative to modern printers, restricting complex label designs or large font libraries. Connectivity options do not include built-in Ethernet or wireless interfaces, which limits network flexibility without additional adapters. The printer lacks advanced user interface features such as a touchscreen, relying on basic control buttons and LEDs. Finally, its legacy technology base may face compatibility issues with newer operating systems or software without updated drivers.
