Quick view

The Zebra GX420t is a thermal transfer and direct thermal desktop label printer designed for office and light industrial environments. It features a 32-bit 133 MHz processor that ensures efficient label printing with fast processing speeds. The printer supports a maximum print resolution of 203 dpi (8 dots/mm) for sharp and clear barcode and text output. The GX420t supports various media sizes, with a maximum print width of 4.09 inches (104 mm) and a maximum print length of 39 inches. It offers multiple connectivity options including USB 2.0, serial RS-232, and parallel interfaces, allowing versatile integration into existing systems. The printer includes a 203 dpi thermal printhead with an automatic calibration system to optimize print quality based on media type and condition.

Additional features include a user-friendly LCD status indicator for easy monitoring, and compatibility with Zebra’s EPL and ZPL programming languages. The device uses 4 MB Flash memory and 8 MB SDRAM to store label formats and graphics. Its construction supports a roll media capacity of up to 5 inches and is known for quiet operation and reliability in small to medium batch printing workflows.

The GX420t offers compact desktop design making it suitable for constrained office spaces. Its dual-mode (thermal transfer and direct thermal) capability provides flexibility for different labeling needs and media types. The printer supports multiple connectivity options including USB, serial, and parallel ports to ensure compatibility with various software and hardware environments. It has an easy-to-use front control panel with status indicators simplifying printer management and troubleshooting. The Zebra GX420t provides high reliability with Zebra’s proven print engine technology and automatic calibration. Additionally, the device supports a broad range of media widths and types enabling versatile label printing for barcoding, shipping, and product identification.

The GX420t has a maximum print speed of up to 4 inches per second, which might be slower compared to some industrial printers for high-volume deployments. Its print resolution is limited to 203 dpi, which may not suffice for applications requiring very fine print detail. The memory capacity, although adequate for standard labels, can be constrained when handling very complex graphics or large label formats. It does not natively support wireless connectivity options such as Wi-Fi or Bluetooth, which might limit mobility and remote printing capabilities. The printer’s label roll capacity of 5 inches may require frequent media replacement in high-demand settings. Additionally, the device is primarily designed for desktop use and may not be robust enough for harsh industrial environments requiring heavy-duty printer hardware.
