export file format in the vendor method of payment in AX?

Hi, when we generate the ‘generate payment’ form the payment journal, the sample data allow us to print the check layout in the screen. I am not 100% sure if we need to set up a file format that I want to clear. We use check payment and so i created a check layout for paying Bank accounts. now will I be able to print a check layout

or do I need to define the export fileformat etc.,

somewhere i read that pointed to GL → reports → transactions → export to and then here.
