some code fragment would be very helpful

I am not sure about how much your project depends on 2008 R2, but try to remove your dependency on R2 and reference only SQL 2012 components, if that is applicable.

very incomplete code you have here for anyone to help. Just make sure that you are creating an instance of the report and assigning it before running the code above.

The solution depends highly on the method / programming language you are using to print in the first place. More details would surely help others help you :)
