Re: How to print in full page without margins

Hi Ron,
I found a great set of codes and article that you post in the other forum
for getting the printer's hard margin throught GetDeviceCaps.

I was able to retrieve the correct hard margins through GetDeviceCaps but I
am unable to tell the printer to use that hard margins to draw maximum
printable area. I have the following code for setting the margins.

IntPtr hDc = new IntPtr();
hDc = e.Graphics.GetHdc();
PrintUtil.GetHardMargins(hDc, ref leftHardMargin, ref topHardMargin, ref
rightHardMargin, ref bottomHardMargin);
e.Graphics.ReleaseHdc(hDc);



leftMargin = Convert.ToInt32(leftHardMargin);
topMargin = Convert.ToInt32(topHardMargin);
rightMargin = Convert.ToInt32(rightHardMargin);
bottomMargin = Convert.ToInt32(bottomHardMargin);

this.DefaultPageSettings.Margins = new
Margins(leftMargin,leftMargin,topMargin,topMargin);

this.OriginAtMargins = true;
Rectangle myRect = new Rectangle(leftMargin, topMargin, rightMargin,
bottomMargin);


e.Graphics.DrawRectangle(Pens.Black, myRect );

The printer cuts of the right side of the rectangle box. And the printer's
left offeset seems to be wider than the printer's actual printable area which
I tested with left and right margin set to zero. So I can see where the
printer start printing on the page.

I have tried so many ways of setting printers margins but none seems to work.

Furthermore, my way of setting margins have different effects on different
printers.

Please help me figure out what is making this weird behavior.

Thanks in advance
