Hey Jeff,
In V1.0 of the .Net framework, Microsoft did not take
account for the hard margins of the printer. This
means that if the hard margin for the printer was
inset by 1/4 of an inch then a margin of 1 inch would
actually be inset by 1.25 inches. Nice huh? :)
In V1.1 of the framework, they have added an
OriginAtMargins property that when true will take the
hard margin into account when setting the actual
margin so that the margin is physically 1 inch from
the edge of the printer.
You will probably have to pinvoke to get the offset
you require to re-adjust your placement of objects.
