Multiple print jobs to brother QL-800

[Abhi0725]

We are using the brother_ql library to print jobs.

The application connects to server via websocket and receives print jobs.

The issue occurs when there is say more than 3 jobs at once.

I found this open issue: #85

The solution to remove self.dev.set_configuration() or prepend it with self.dev.reset() doesn't work and in fact throws the following error after 3-4 jobs has been printed:

Access denied (insufficient permissions)

On the other hand when I run the code without removing the above mentioned line then I get:

No such device (It may have been disconnected)

Please note I am running the python code via electron app and hence the JS file is showing the error but in fact this is coming from the output of python file.
