1 Year WarrantyIncludedThe Zebra GK420t 203 dpi Thermal Transfer Label Printer (GK42-102210-000) is a compact desktop barcode and label printer made for companies that require dependable, regular labeling without the expense or size of a complete industrial printer. This model combines 203 dpi thermal transfer printing with an intuitive clamshell design that makes media loading and maintenance easier. It is designed for retail, healthcare, light manufacturing and office settings. Zebra's acclaimed print engine produces consistent barcodes, shipping labels, shelf tags and asset labels that scan cleanly and appear professional, and its compact size makes it comfortable on busy counters or workstations. Depending on the application, you can select between more straightforward direct thermal stock and durable ribbon-based labels due to the GK420t's compatibility for both thermal transfer and direct thermal printing. The majority of common barcode, text and basic graphic requirements are best served by the 203 dpi resolution and regular labeling chores may be completed quickly with print speeds of up to 4 ips. A single button interface and front-panel status LEDs make operations easier for non-technical employees, cutting down on training time and user error. The GK42–102210–000 configuration is a suitable fit for both current and legacy systems because it usually has serial/parallel and USB connectivity (the precise mix can vary by location). The GK420t easily interacts with third-party applications and current Zebra label workflows because to its compatibility for the EPL and ZPL programming languages.
