Fifa 12 PS3 controller configuration handout?
Solution 1:
In this thread john_wisdom shares a fan-made manual that seems to fit your needs. The current PS3 version can be found here.
Solution 2:
I don't know if there is an existing PDF for this already, but all the information you need to create one is in the game menu:
Customize FIFA -> Settings -> Controls -> Button Help
There you can find all commands for basic moves, skill moves and celebrations.
As you will see, the number of moves is quite large, so a PDF might not be exactly helpful. Learn the basic moves and keep experimenting. If you want to find out how a certain move works, look it up.
Fifa controls are mostly an experience thing, you will not be able to master all moves at once just because you have a big PDF of commands. ;)
