Re: How to print in full page without margins

Judge,
You may be seeing the way the rectangle is being drawn. Try drawing the
rectangle with the left and bottom 1 less than the generated amounts. I've
never tried the OriginAtMargins offset though. I just normally to a
TranslateTransform by the negative of the left and top margins and then draw
as normal. When I have output that may overflow the printer's hard margins
I test the scaling necessary to fit into the drawn area and do a scale on
the drawing as well.
You might want to try doing the TranslateTransform on the Graphics to
see how that works as well.
