Overview

QZ Tray is a third-party desktop printing utility that Amazon has integrated directly into Seller Central to streamline the shipping label printing process. The tool addresses longstanding browser-based printing limitations by enabling direct communication between Seller Central and your local printers, allowing sellers to print shipping labels with a single click rather than navigating through download-and-print workflows.

Key Points / What Sellers Need to Know

• One-click printing — QZ Tray lets you print shipping labels purchased through Buy Shipping directly from Seller Central without extra steps, saving time on every order you fulfill.
• Multiple format support — The tool supports PDF, ZPL, and PNG label formats, covering both standard desktop printers and thermal label printers commonly used in fulfillment operations.
• Printer assignment by format — You can designate specific printers for each label format, so ZPL labels automatically route to your thermal printer while PDF labels go to your standard printer.
• Browser printing issues resolved — QZ Tray bypasses common browser-based printing problems that have frustrated sellers, including formatting errors, scaling issues, and print dialog interruptions.
• Integration with Buy Shipping — The tool works seamlessly within Amazon's Buy Shipping service, which is the recommended way to purchase and manage shipping labels in Seller Central.

How QZ Tray Works

QZ Tray operates as a lightweight background application on your computer that creates a bridge between your web browser and your local printers. Once installed and configured, it communicates with Seller Central through a secure local connection, receiving print jobs directly from the Amazon interface. When you purchase a shipping label through Buy Shipping, the label data is sent to QZ Tray, which routes it to the correct printer based on your configured format preferences. This eliminates the need to download label files, open them in a separate application, and manually send them to the printer — a workflow that adds unnecessary steps and introduces opportunities for errors.
