- Open the Zebra Printer Setup Utility app, which is also named the Printer Setup app on your iPhone.
- With your printer connected, tap on Print Quality. If your printer is not already connected, you must first tap on the Hamburger Menu Icon, then tap on the printer under the Discovered Printers section. Once it’s connected, the side menu should hide and return you to the Printer Setup screen.
- Change the Speed to 4 and the Darkness to 28.
- Now, tap Print Sample Label. If the darkness isn’t to your liking, it can be increased up to 30. If you’re happy with it, then tap Next.
- Then on the final screen, tap Apply to save the changes.
- Try printing another label to see the result. If it’s still too light or too dark, go through the steps above once again to get it just right for you.
