Quick view

The Zebra GX420T is a reliable thermal transfer desktop printer designed for medium volume label printing tasks. It features a 203 dpi (8 dots/mm) print resolution enabling high-quality barcode and label printing. The printer supports a print width up to 4.09 inches and can print at speeds of up to 4 inches per second. It includes a thermal transfer mechanism, requiring ribbon and compatible media, suitable for producing durable, long-lasting labels. Connectivity options typically include USB and serial ports, with optional Ethernet for network integration. The printer's compact design and ease of media loading make it suitable for offices, warehouses, and retail environments.

The GX420T also supports EPL and ZPL programming languages for flexible label format design and integration. Its firmware supports multiple font types and barcode symbologies, facilitating diverse printing applications. The device operates with Zebra’s Link-OS environment (in later firmware versions) and supports remote management and configuration. The printer’s exterior is crafted from ABS plastic, providing durability while maintaining a lightweight form factor suitable for desktop use.

The GX420T offers excellent print quality with its 203 dpi printhead, suitable for detailed barcodes and labels. It supports both direct thermal and thermal transfer printing, expanding its media compatibility. The device is compact and space-saving, ideal for limited office or workspace setups. Easy media loading and user-friendly interface reduce downtime and simplify operation. Versatility in connectivity including USB, serial, and optional Ethernet enables flexible deployment. Its compatibility with EPL and ZPL languages allows integration into many existing labeling systems.

The print speed of up to 4 inches per second may be slower compared to some modern models, limiting throughput in high-volume scenarios. It lacks built-in Wi-Fi connectivity, requiring additional adapters for wireless printing. The maximum print width of approximately 4.09 inches is limited for wider label formats. The memory size is relatively modest, which can restrict complex label formatting. The device does not support color printing as it is strictly monochrome thermal technology. Limited firmware updates since release may reduce new features or enhancements over time.
