# Zebra label printer setup

> Configure paper size on Zebra label printers for shipping labels

Zebra label printers such as the ZD421d, ZD420d, ZD220, and GK420d need to be configured with the correct paper size before printing shipping labels. The paper size should be set to **102x192mm** or **100x150mm** depending on the labels you are using.
