Confused about printing, pagebounds, and printer resolution

[Chris Dunaway]

When using PrintDocument to print something, if I check the PageBounds
property of the PrintPageEventArgs object, it shows the rectangle to be
850 x 1100, or 100 dpi. But when I check the value of the
PrintDocument.PrinterSettings.DefaultPageSettings.PrinterResolution.X
property for the printer in question it shows 600 dpi?

If I perform the following:

e.Graphics.FillRectangle(Brushes.Gainsboro, 40, 40, 500, 100);

in the PrintPage event, I get a gray rectangle that is exactly 5 inches
by 1 inch, or 100 dpi.

What is the relationship of the rectangle returned by the PageBounds
property to the dpi of the printer?

I tried changing the resolution of the printer but it still seemed to
print at 100 dpi.

Can anyone clear this up for me?

Thanks

Set the pageunit property in the PrintPage event - I have my data stored in
inches, so I set it like this:

e.Graphics.PageUnit = GraphicsUnit.Inch; // or whatever unit you want.

If you do this, you don't have to worry about the DPI of the printer.
