Tim Waugh aaae0ca8ba New cloudprint GTK+ print module for Google Cloud Print.
This is a web service provided by Google that allows people to
share their printers (https://www.google.com/cloudprint/learn/).

In addition to being able to print to printers shared on Google Cloud
Print, there is an equivalent of "Print to file" in the form of "Save to
Google Drive".

The cloudprint module uses gnome-online-accounts to obtain the OAuth 2.0
access token for the Google account.

Currently it can discover available printers, get simple details about
them such as display name and status, and submit jobs without any
special options.
