Zebra GK420 Bar Code Printer

Zebra GK420 Barcode Printer

The Zebra GK420 barcode printers are a perfect fit for desktops in the retail, healthcare, manufacturing, security, and travel/ hospitality industries. Compact and reliable, the Zebra GK420 printers are known for their small size and dependable performance, which is why they are widely used in many environments.

Not every company requires high-volume barcode printers. That’s the reason Zebra designed the G-Series models. Not only does their footprint lend itself for areas where space is at a premium; they reliably meet the demands of companies with low-to-medium print volumes. And, they are affordably priced for businesses on a budget.

Zebra gave these printers fast print speeds of 5 inches per second. Then, they equipped them with standard features that encourage efficiency, including 8 MB of SDRAM, a maximum print width of 4.09,” and 203 dpi print resolution. Certain GK420 models include peelers and Bluetooth or Ethernet connectivity in lieu of the standard USB, serial, and parallel ports. And, they enable you to choose from direct thermal or thermal transfer print modes to handle an assortment of jobs.

All desktop barcode printers include both EPL and ZPL print languages for easy integration into existing systems. It’s also simple to load ribbons and calibrate media in the Zebra GK420 desktop barcode printers.
