Are you facing some issues while configuring your Zebra GK420D printer?

Then you came to the right Help article! ๐Ÿ™Œ

๐Ÿ“Œ Please keep in mind this guide only refers to Windows system, but don't desperate MAC users, we thought about you too, more updates to come!

Let's dig in ๐Ÿ”ง

1. Select the 'Devices and Printers' option within the 'Control Panel' of the computer

3. In Printing defaults set Paper Format to 'inch', Size Width to '4.00' and Size Height to '6.00'

4. You will now need to calibrate your printer. To do this click on the 'Tools' tab.

Then click 'Action' and 'Calibrate media' then click 'Send' at the bottom of the page.

๐Ÿ“Œ Please note: This will feed some blank labels through your printer.

5. Next click on the Dithering tab and select none.

Then click 'Apply' and 'OK' and you will be returned to the 'Advanced' screen where you originally selected 'Printing Defaults'

๐Ÿ“Œ Please note: Setting Dithering to None ensures that the newer 2D barcode is printed properly and will scan through the network.

Any other setting here reduces the accuracy of the 2D barcode to the point where the labels you produce may not scan through the Royal Mail network.

6. Now that the printer has been calibrated, you are good to go printing your Royal Mail 2D barcode label!

And that's it ๐ŸŽˆ
