Summary

This app (or collection of apps) has been built to demonstrate the use of the Google Cloud Print and Core libraries.

It consists of two components:

  1. A test harness that provides a UI for performing all of the Google Cloud Print API calls.
  2. An implementation of the library that allows Account attachments to be printed to the Google Drive printer via Google Cloud Print.

Note: Currently, no test coverage for the sample apps has been provided.
