Google Cloud Print is a free service that is used to send, on the Google servers, the files that will be printed on the preset printers. Therefore, the print is performed via Internet.
To use the Google Cloud Print service:
- Configure the printers on the site of Google Cloud Print.
- In the application, use GglPrintDocument.
Operating mode on the phone
GglPrintDocument opens several pages in the current application.
- If the user is not connected, a page for connecting to Google is displayed. In this page, you must type the login and password of the Google account that was used to define the printers.
- A page proposes the different available printers. All you have to do is select the requested printer to define the print options and to start the final print.
The call to this function modifies the permissions required by the application.
Required permission: INTERNET: this permission allows the applications to open the network sockets.
