Hi,
here is the case:
qztray (2.1.*) is working fine on linux and Windows 10 professional, but stopped running on Win 10 Home in the follwoing cases
  • It is responding OK on first print i.e. before I save the certificate. So if I don't save the certificate and click "allow" every time it is workign fine, but once saved it returns error.
  • It opens and closses connection to qztray but returns unkown printing error. And nothing interesting in the qztray log either.
  • It works ok on getting the printing list.
More info:
  • I've tried running and also installing qztray as an administrator, and that doesn't solve the problem.
  • The allowed.dat file in AppData/Roamin/qz is OK, but the one in ProgramData is 0k.
Hope someone have an idea.

Can you please send a copy of the logs?

If they contain sensitive data, you can send them to sup...@qz.io and we'll keep them off of the list.

Best regards,

Hi Tres,

Reason 1005 is pretty vague, quoting:

1005 - No Status Received (Reserved.) Indicates that no status code was provided even though one was expected.

Can you run from the command line and see if the JVM is crashing?


At a glance, I don't see anything that's wrong, but with any websocket error, there's two sides and we're only seeing the server side.

To that point, any logs from the browser are greatly appreciated.

The browser logs don't help much either, they seem to be obfuscated.

Are you on qz-tray version 2.1.1-1?  There was a race condition we patched with getVersion() which may be occurring on some machines and not others.

This is version 2.1.0, but I tried with 2.1.1 and the result is the same.

Right, I've asked if you've tried 2.1.1-1 as it fixes a race condition with getVersion, which is one of the last API calls showing in your logs.

Your reply says you've tried 2.1.0 and 2.1.1, neither versions which were mentioned in my reply.  My reply specifically mentions 2.1.1-1 which is a patch to fix a race condition.

Anyway, you should use the demo page and test the API out there.  https://demo.qz.io.  That's going to get better logs and it uses the latest QZ Tray API.

We have not tried it in on our app. We will do this tommorow.
I've tried demo.qz.io with qz 2.1.1-1, but as in does not allow me to save the certificate as allowed, that does not let me test it right, because if not saved it works fine in either version.

Right, I've asked if you've tried 2.1.1-1 as it fixes a race condition with getVersion, which is one of the last API calls showing in your logs.

Your reply says you've tried 2.1.0 and 2.1.1, neither versions which were mentioned in my reply.  My reply specifically mentions 2.1.1-1 which is a patch to fix a race condition.

Anyway, you should use the demo page and test the API out there.  https://demo.qz.io.  That's going to get better logs and it uses the latest QZ Tray API.

Well, getVersion() shows a blank signature, so you might have an incorrectly configured setSignaturePromise(), but the logs don't really help and we have a strict policy against assisting with licence removal on this mailing list.  The easiest way to test this is following this YouTube tutorial: https://www.youtube.com/watch?v=X72y6ZZTWzE

This will at least establish a baseline of what's working in regards to the licensing.

Again, we don't help with licensing on this community mailing list.  If interested, we have premium support options available on our buy page and we can likely have this working in less than an hour.

Best of regards,
