How can i print a A4 sized document which contains both dynamic images and data?

Question

Hi,

I currently have an application which allows a user to capture and change required data for orders which come thorough on a daily basis. My next challenge is to print all the relevant data to a A4 sized document as soon as the user saves the orders details. ( Almost like a receipt )

Also the application needs to have the ability to change the layout of the print if needed.

I am unsure as to how to go about achieving this. I have tried to create a new form and populate it once it is initialized however i cannot size the form to A4.

Is there any other method which is more efficient in achieving this?

Thanks
