QZ Tray is a small application that acts as a bridge between your web browser and your local printer. Because web browsers have limited access to hardware devices for security reasons, AccelerList uses QZ Tray to communicate directly with your printer.
Without QZ Tray, AccelerList would not be able to automatically send labels to your printer.
What QZ Tray Does
When you print a label from AccelerList:
AccelerList generates the label.
The browser sends the print request to QZ Tray.
QZ Tray communicates directly with your printer.
The label is printed automatically using the correct printer settings.

Why Is QZ Tray Required?
Modern browsers cannot directly access local printers for security reasons. QZ Tray provides a secure connection between AccelerList and your computer's printers, allowing printing to happen automatically and efficiently.
What Happens If QZ Tray Is Not Installed?
You may experience:
Printers not appearing in AccelerList
Print buttons not working
Labels downloading as PDFs instead of printing automatically
Printing errors or connection issues
