Connect to cups server (which has basic authentication enabled) using pycups library

[rival123]

I am using cups version 2.2.10. Cups server is Basic Authentication enabled. And I am using pycups = 2.0.1 as a client library to connect to cups server. But I am unable to make successful connection using pycups because it doesn't provide support for adding password.
We can set server, port and user but not able to find how we can set Password.

cups.setServer(self.configuration.cups_server)
cups.setPort(self.configuration.cups_port)
cups.setUser(self.configuration.cups_user)

I also tried adding callback but that also doesn't seem to work-

def password(self):
return self.configuration.cups_user
cups.setPasswordCB(self.password)

Getting Unauthorized error every time. Is there any way I can make a connection using pycups when cups server has Basic Authentication Enabled?
