There are two locations from which you can generate reports.
1) From the game page - the report from that page is the "Single Game Report" and is limited to the current game and the fixed format of the report.
2) From the "Reports" tab. This tab is located along the bottom of most screens. If you are in a game edit screen you need to click the "Done" button in the upper left corner to see the tabs along the bottom of the screen.
Select the Reports button at the bottom.
For an example - select the "Single Game" report.
Set the options you want. Then select the "Show" button in the upper right corner.
You can export this with the button in the upper right corner.
You will need an "AirPrint" capable printer to print from an iOS device. You will need an email account set up to email the report using Apple's email app.
