Printing will depend on what device your using. If on Android, you will have to install your printer vendor's app to be able to export the project out from PS Touch for printing, for example.

You should be able to email or saving to your device simply by tapping the export icon (5th icon from the upper right in the project selection user interface) > Share  (or "Save to" if saving to device) > selecting a project and the file format and then tapping OK.
