Zebra GK420t Barcode Label Printer

Zebra GK420t Barcode Label Printer

The Zebra GK420t Thermal transfer printer uses Zebra's easy ribbon-loading thermal transfer technology to produce crisp, longlasting 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.
