Calibrating Your Zebra Printer: How to Do It?

In this blog, we will explain how you can calibrate your Zebra printer. If you are using a Zebra printer to print shipping labels, for example, it is important that it is well calibrated. In this guide, we will cover step by step how you can calibrate your Zebra printer for both Windows and Mac. We will show you how to set the size of your labels and how to further calibrate the printer. We will also show you how to ensure that your printer is properly set up on your computer. This way, you can confidently start printing shipping labels.

In this blog, we have used the Zebra GK420D label printer as an example, but the process is the same for every Zebra printer, so don't worry about that. Just make sure that the name of your printer may differ from the name of the printer used in this guide.

Calibrating a Zebra printer is a little different on Mac and Windows systems. Below, we have broken down both options for you so you can easily follow the installation procedure for Mac or Windows.
