Print html document

Hi, I am not sure if I am asking my question in the right section. I have designed an html document similar to a layout in my FileMaker Pro application so that I can distribute it electronically with dynamic data from my application. The problem is printing the html document. I want to add code inside the html document such that the document should print correctly with all the alignment. In other words I want to manage the page setup inside the html document such that the document should fit in a A4 page, portrait, arrange the left and right margins etc. This could be done using the "@page normal { size : <>}" but I don't know where to keep this code in the html document. I have seen big documents on internet where the print is perfect and the document shrinks automaticaly to fit the page size.

Is there any setting which we can do? Any solution is most welcome.

Thanks,
