You can print your Google documents and spreadsheets from your mobile browser using Google Cloud Print.
Set up Cloud Print
Before you begin, be sure you have set up your printer to work with Google Cloud Print.
When you use Google Cloud print from your mobile browser, your document or spreadsheet will be printed with your printer's default settings.
