Google Cloud Print to mobile documents functionality is now extended to mobile spreadsheets with some added additional printing improvements to the desktop version of Google spreadsheets.
- Mobile printing for spreadsheets
Now you can print your spreadsheets to any cloud-connected printer right from your phone by selecting Print... underneath the spreadsheet title. This feature will work on most phones and tablets that support HTML5, such as devices running Android 2.1+ and iOS 3+.
- Improved desktop printing
Added a number of printing options, including spreadsheet titles, sheet names and page numbers. You have control over which of these you want to print.
