Overview
AccelerList uses QZ Tray to enable direct communication between the application and your local printers. Because modern web browsers restrict websites from accessing local hardware for security reasons, QZ Tray serves as a secure bridge that allows AccelerList to send print jobs directly to supported printers.
Without QZ Tray, printing labels would require additional manual steps, making the listing and shipping process slower and less efficient.
What Is QZ Tray?
QZ Tray is a desktop application that runs on your computer and allows web-based applications to communicate with locally installed printers and other hardware devices.
When connected to AccelerList, QZ Tray enables:
Direct label printing
Automatic printer selection
Custom label formatting
Batch printing workflows
Why Is QZ Tray Required?
Direct Printer Access
Web browsers such as Chrome, Edge, Firefox, and Safari do not allow websites to directly control printers. QZ Tray provides a secure connection that allows AccelerList to communicate with your printer without compromising browser security.
Faster Printing
Instead of downloading files and printing them manually, QZ Tray allows you to print labels with just a few clicks directly from AccelerList.
This helps streamline:
FNSKU label printing
Product labels
Merchant Fulfilled tickets
Shipment labels
Accurate Label Formatting
Thermal printers require precise sizing and formatting. QZ Tray helps ensure:
Correct label dimensions
Proper orientation
Consistent barcode placement
Reliable print quality
Support for High-Volume Sellers
Many AccelerList users print hundreds or thousands of labels per day. QZ Tray supports efficient batch printing without requiring users to manually configure each print job.
Supported Printer Types
QZ Tray can be used with many popular printer brands, including:
Dymo LabelWriter printers
Zebra printers
Brother label printers
Rollo printers
Standard laser printers
Standard inkjet printers

Is QZ Tray Safe?
Yes. QZ Tray is designed to securely connect trusted applications with local hardware. It uses signed certificates and secure communication methods to ensure print jobs are transmitted safely between AccelerList and your computer.
Summary
AccelerList uses QZ Tray because modern browsers cannot directly communicate with local printers. QZ Tray provides a secure and reliable connection that enables fast, accurate, and efficient label printing directly from the application, helping sellers streamline their listing, prep, and shipping workflows.
