Google Cloud Print was a Google service that allowed users to print from any Cloud Print-aware application (web, desktop, mobile) on any device in the network cloud to any printer with native support for connecting to cloud print services[2] – without Google having to create and maintain printing subsystems for all the hardware combinations of client devices and printers, and without the users having to install device drivers to the client,[2] but with documents being fully transmitted to Google.
