Install Google Cloud Print in Ubuntu Linux

sudo add-apt-repository ppa:simon-cadman/niftyrepo


sudo apt-get update


sudo apt-get install cupscloudprint


sudo /usr/share/cloudprint-cups/setupcloudprint.py


After it asks for Google Credentials ( it will only do this is the
  first time you have used CUPS CloudPrint, or your credentials are
  invalid ) it will then ask if you wish to add all printers from your
  Google Account.


To make it work with Google's 2 Step Verification system, you must 
create a "Device Specific" password, to do this go to:Google.com>Log 
in with your account>Click on your user name>Security>Edit 
authorizing applications>Enter your account pasword>set the 
password.


If you say ‘Y’ here, it will add all printers that are currently not
  added to your CUPS install.


If you would prefer to add the printers manually, say ‘N’ here, and
  add a printer manually:


Add a new printer ( via http://127.0.0.1:631 or usual interface ) as a
  ‘Google Cloud Print’ network printer. Select the ‘Make’ as Google, and
  ‘Model’ as Cloud Print.
