Quick view

The Zebra GK420t is a thermal transfer desktop label printer designed primarily for office and industrial applications. It features a print width of up to 4.09 inches and print speeds up to 5 inches per second, leveraging its thermal transfer printing technology for durable and high-quality labels. The device operates with a 32-bit ARM processor, enabling efficient label processing and rapid printing without compromising quality. It supports various connectivity options, including USB 2.0, Serial, and Parallel interfaces, allowing integration with diverse systems. The printer is compatible with multiple media types and widths, ranging from 0.79 to 4.4 inches in width. Zebra’s EPL and ZPL programming languages enable flexible label design and printing customization.

Additionally, the GK420t includes an intuitive LCD display for simple navigation and status monitoring, with internal memory capable of storing fonts and graphics. The compact design is optimized for space-constrained environments, making it suitable for retail, healthcare, and logistics labeling applications.

The GK420t excels through its reliable thermal transfer printing technology, delivering long-lasting labels resistant to smudging and wear. Its compact and lightweight design fits easily into tight workspaces, ideal for office and industrial environments. The printer offers flexible connectivity options, including USB, serial, and parallel ports, enabling seamless integration. High-resolution printing at 203 dpi ensures clear and precise text and barcode output. The ability to support a broad range of media types and widths provides versatility for various labeling needs. Additionally, Zebra’s programming language compatibility allows advanced customization and easy integration in existing systems.

The GK420t’s printing speed, capped at 5 inches per second, may not suffice for high-volume industrial labeling demands. Its maximum print width of 4.09 inches limits applications requiring wider labels. The printer’s reliance on thermal transfer ribbons introduces ongoing consumable costs compared to direct thermal alternatives. Some older interface options like parallel and serial ports may not support modern connectivity standards such as Ethernet or Wi-Fi without additional adapters. The lack of color printing restricts it exclusively to monochrome labels. Moreover, the device does not support mobile or cloud-based printing natively, which may limit flexibility in some office environments.
