pycups module for CUPS prinitng

Question

I am using the python cups module to list the available destinations. And everything work perfectly. I've installed the pycups using sudo apt-get install pycups.

import cups

conn = cups.Connection()
printers = conn.getPrinters()
for p in printers:
    print(p)
    print(printers[p],["device-uri"])

The problem is that I am not finding a documentation for this module and what are the methods that can be used so can implement other functionalities.

Do you have an idea where I can find the documentation ?

Thank you in advance.
