Best value in a Desktop Printer

The Zebra GK420T Thermal transfer printer uses Zebras easy ribbon-loading thermal transfer technology to produce crisp, long lasting label images, or direct thermal technology to print receipts and labels for indoor, short-term use. The GK420T is well-suited to any industry, and provides the same print speeds and connectivity options as the GK420D.
