Is there a way to determine what check form was used for a specific payroll run

We have a customer that says their ssn's are mased on top but not on the bottom check stub.  We have several versions of the payroll check forms due to different requirements.  Is there a way to know which form they actually used?  I can see thier default in the bank setup, but they can change that when printing.  I just need to see what they used.

Thank you!
