Zebra ZD621 Driver Download, Update, and Install on Windows

Do you need high-performance, on-demand label printing from your Zebra ZD621 printer, or have you encountered errors like “Unknown device” that have made it dysfunctional? 

The “Unknown device” error usually appears in Windows when your computer cannot properly identify or communicate with the printer, often due to a missing or incorrect driver. If you see this error in Device Manager or after connecting your printer, this guide will help you. Learning how to download and install the correct and compatible Zebra ZD621 driver for Windows 11/10 can help you get the best output from your printer.

Without the driver, this communication stops, causing problems like the printer not being found or other common printer issues. 

Hence, this article walks you through the most efficient methods to download the Zebra ZD621 driver, install it, and update it for the best performance.

If this does not solve the problem, you can check the specific solutions to your printer problem.

Moreover, adjust the darkness setting in your printer driver to make sure the print is neither too dark nor too light. You can find these settings under “Printer Properties” -> “Printing Preferences” in the driver. 

Additionally, check the print speed to ensure it is not too high to get optimal print quality. 

Media out/improper calibration

Your printer needs calibration if it stops feeding or prints on the incorrect spot. To perform the Zebra ZD621 calibration, you can follow the steps below. 

• Open the Zebra Utility App.

• Lastly, click “Next” and then click “Apply Settings.”

If the system does not recognize your printer, check the network connection and ensure your printer is connected to the right network, update the driver, or reinstall the drivers. Additionally, ensure your printer settings are configured correctly.
