Problems printing label

[VCG Comercio]

Good morning, I'm having trouble printing marketplace labels (Mercado Livre, Shopee...) using your program. When I print from Windows, outside of your program, it prints normally. However, when I print through Bling using your program, the label freezes. I've been trying to resolve this for 30 days, both with Bling and with technicians in person, and we've concluded that the problem is with QZ Tray. I would like to know if you can help me.

Sorry for the trouble.

If there's really a problem with QZ-Tray and Bling, then a representative from Bling should have reached out to us by now. They are a paid client, and we prioritize their support tickets. We have not received any such communication as of this writing.

Bling should never tell you to raise a support ticket to us by yourself. We can probably help you figure out what's wrong, but we can't necessarily make it work for Bling's website.

Please check the functionality of QZ-Tray without Bling by navigating to https://demo.qz.io and clicking the "Pixel Printing" tab (screenshot attached).

Search for your printer, and once you have it selected, try printing a PDF to it. 

Did it print as expected? 

Next, please gather logs from your machine and send them in an email to sup...@qz.io (this email group is public, so I don't want you to share any private information here):

https://qz.io/docs/faq#logs

From the QZ Tray Icon:
Advanced, Troubleshooting, Zip Logs (To Desktop), attach zip file in email

Please also include the operating system (Windows, MacOS, Linux) and version, as well as the make and model of the printer, and how it is connected (USB, ethernet, WiFi).

We look forward to hearing from you.

Kind regards,

Lite Finocchiaro

VP, QZ Industries

The logs suggest Bling needs to check for websocket closed events.  Bling, please reach out to us rather than asking your users to escalate these issues for you.
