Hi ,I am a developer and i am newbie to odoo .

I am trying to connect to Epson T20 receipt printert odoo V11 - POS  through hardware proxy without posbox .I have Installed

1.ESC/POS Hardware Driver

2.Hardware Proxy

And also Python Modules

1.pyserial

2.pyusb 1.0.0b1

3.qrcode

Access rights are perfectly set. My odoo logs shows "connected to Epson T20"  and throws an exception "TypeError: Can't convert 'TypeError' object to str implicitly" . On checking hw_proxy status on browser It shows "internal server error" and the odoo log shows "Runtime error :cannot set daemon process of the active thread ".

  I discovered that it is the python version that creates this error on type conversion  .Then I tried switching to python2.7 then it worked fine. Can you say Why is there an issue while using Python 3?
