Pdf Margin

[makah]

Hi Jason,
I have a problem with top and bottom margin page when i transform a docx document in a pdf document.
In docx document i have a strict margin and, when i transform in pdf, i have new margin that is bigger than original.
I have tried to set manually w:pgMar tag and if a set a big margin (like w:top="6000") then pdf transformation works fine (set the same big margin) but if a set a small margin (w:top="80") then a i have a standard margin.
