Compact Zebra G-Series desktop printers can print media up to 4 inches wide, offering extremely fast printing speeds and top-notch printing performance.
Whether it’s the basic GK model or the feature-rich GX model, G-Series printers consistently demonstrate reliability, ruggedness, and flexibility, meeting virtually all small to medium volume printing applications and budget requirements.
The G-series GK models uphold Zebra’s tradition of durability and reliability, offering the highest value among all basic desktop thermal printers. If you prioritize space efficiency, the smallest 4-inch direct thermal desktop printers (GK420t and GK420d) will meet your needs; if you prioritize time efficiency, the direct thermal/thermal transfer printer (GK420t) with its convenient ribbon loading system is the ideal choice.
The Zebra GK420t direct heating/thermal transfer printer utilizes Zebra’s convenient ribbon-loaded thermal transfer technology, enabling the printing of long-lasting hard label images as well as short-term indoor receipts and labels. Suitable for any industry environment, the GK420t offers fast printing speeds (up to 5 inches per second) and a variety of connectivity options, including USB/serial interfaces and optional 10/100 Ethernet.
