Google Cloud Print is a service that lets you print a document using any Cloud Print-enabled printer over the web. If you have a normal (classic) printer, you can use that too. You just need to connect your PC to the printer and enable Google Cloud Print using the Chrome browser on it. To do this, go to your Chrome Settings page, click on Show Advanced Settings and then on the Add Printers button under the Google Cloud Print heading.
This will display a list of printers your PC has access to and you can select one or more of them.
Next, you need to install the Google Cloud Print app on your Android device. Once you do this, you can print from your device using the Share option. For example, to print a webpage from Chrome, select Share and then Cloud Print.
This will display a list of printers you can print to. You can also save the webpage to your Google Drive.
