Updated over a week ago

Here's a quick guide to install QZ Tray on Windows.

Let's see how to do it! ๐ŸŽ‰
๐Ÿ‘‰Before starting, check these 4 steps:

  1. Use Chrome as browser.

  2. Set ZPL format as default from Carriers > Edit for each carrier you connected.

  3. Create a manual shipment for testing following this guide.

  4. Install latest Java update from this link:

โš ๏ธ Verify that your printer supports ZPL print format, in case not, you can stil set the Carriers connected on PDF format.

1. Download QZ Tray

From Label Creator > Shipping Labels, click on the first blue button Print > Print on Zebra.
๐Ÿ’ก Note: if the Print on Zebra button is not clickable, it means that the label selected is a PDF.
You should check the format selected on ย Carriers > Edit and crea a new label.

  • You'll see a banner appearing on the right. Click on Windows to start the download automatically from it.

  • Once downloaded, click on QZ Tray file and start the installation.ย 

  • If you haven't done it yet, QZ Tray will ask you to install latest Java update at this link, installation will stop and you'll need to restart it by clicking on file again.ย 

  • Once completed, you can refresh Shipping Labels page, select the orders and click on Print > Print on Zebra > Print.

๐Ÿ’ก Note: Remember to set up Automatically start clicking on the QZ Tray icon in the toolbar, in order to open it when you turn on your computer.

2. How to print multiple ZPL Labels ๐Ÿ–จ๏ธ

  • To print multiple ZPL labels, select the orders you'd like to print and click on Print > Print on Zebra.

  • From the window that pops up, click on Print. If you want to change printer, click on Printer Settings and click on the X next to the printer name.

๐Ÿ‘‰Note: You can still print your ZPL lables in PDF, selecting orders and by clicking on Print > Print ZPL in PDF.

3. How to print ZPL Labels singularly ๐Ÿ–จ๏ธ

To print your ZPL labels singularly, just click on the violet icon under Documentation:

๐Ÿ“Œ Are you facing QZ TRAY INVALID SIGNATURE Error message? Don't worry! Verify if your Antivirus is active, then try to uninstall QZ Tray and install it again from Shipping Label > Print > Print on Zebra.

๐Ÿ“Œ PLEASE NOTE: QZ Tray is a singleton application and it cannot support multiple simultaneous instances on the same machine because QZ Tray uses a localhost websocket connection (wss://) from the browser to a single port on the PC. If a second instance of QZ Tray were allowed, the websocket would only ever succeed to the first available port, rendering the second instance useless.

Done! ๐ŸŽ‰
