Zebra GK420t on Mac — Setup & Label Printing with JetLabel

Works on Mac with the macOS driver

The Zebra GK420t is a 203 dpi label printer from Zebra that uses ZPL. On Mac, JetLabel prints through the macOS printing system: install the macOS driver from Zebra, add the printer in System Settings and choose it in JetLabel. On iPhone and iPad, JetLabel can send ZPL directly over the network (port 9100) if your model has Ethernet or Wi-Fi.

Printing from iPhone and iPad

JetLabel on iOS and iPadOS supports AirPrint and suitably configured network label printers using supported protocols. Check the printer and its network configuration before printing.

Each model page shows whether the printer works on Mac with its macOS driver and whether direct network printing from iPhone and iPad is possible. The ratings are based on manufacturer specifications. Brother QL and Bluetooth direct printing are not supported on iOS.

Does the Zebra GK420t work on macOS?

Yes, with the macOS driver from Zebra. JetLabel prints through the macOS printing system; on Mac it does not send printer commands directly. This assessment is based on the manufacturer’s specifications, not on a test by JetLabel. Try it with your printer during the 7-day trial.

And on iPhone and iPad?

On iPhone and iPad, JetLabel can send ZPL directly over the network (port 9100) if your model has Ethernet or Wi-Fi.

FAQ

About the Zebra GK420t

No. JetLabel prints on Mac through the macOS printing system, so the Zebra GK420t needs a working macOS driver.

On iPhone and iPad, JetLabel can send ZPL directly over the network (port 9100) if your model has Ethernet or Wi-Fi.
