Hi Thunis,
If by decoration border you mean the document's frame border, you can hide it prior to printing and restore it afterwards. To hide the frame border of the document you can use the following line of code:
document.BackgroundStyle.FrameStyle.Visible = false;
To restore the frame border after printing you should set the Visible property back to true.
If you mean something else, please elaborate.
Best Regards,
