I do not understand.

Hello,

I have a table on a A4 paper format.  Each cell has fixed Column and row sizes.   This works fine.

The table is suposed to fill an entire page. When my PDF is created, I display with Acrobat and it seems pretty good.
I don't see any margin. So my table fills entirely my page.

Now when  I print on a A4 paper, I still have margins : top, (2mm) bottom (12 mm), right and left (5mm).

If I measure the table height, it is only 283 mm instead of 297mm.
I do not understand.  Any idea ?

Thanks
