How to list google cloud printers from specific configured mail id in linux.
for e.g.
if you have installed google cloud printers, and want to list printers from one mail id using python script then
1. navigate to cloudprint-cups configuration files location,
cd /usr/share/cloudprint-cups/
2. create one file listsingleprinter.py
paste below content in to the file,
if __name__ == '__main__': # pragma: no cover
import sys
import os
from auth import Auth
from printermanager import PrinterManager
from ccputils import Utils
Utils.SetupLogging()
mail_is = sys.argv[1]
# line below is replaced on commit
CCPVersion = "20140814.2 000000"
Utils.ShowVersion(CCPVersion)
os.system("echo '%s' >/tmp/.c_mail"%mail_is)
requestors, storage = Auth.SetupAuth(True)
printer_manager = PrinterManager(requestors)
printers = printer_manager.getPrinters()
if printers is None:
print "No Printers Found"
os.system("rm -rf /tmp/.c_mail")
sys.exit(1)
for printer in printers:
print printer.getListDescription()
os.system("rm -rf /tmp/.c_mail")
3. make changes in to auth.py
change in to SetupAuth function
@staticmethod

Args:
interactive: boolean, when set to true can prompt user, otherwise
returns False if authentication fails
Returns:

of storage
