Most printer can not print "edge-to-edge". Although
there is not an easy way to find the exact unprintable
area in .Net you can come very close.
See: PrintPageEventArgs.
Graphics.
VisibleClipBounds
You can divide the Width (and height) by two to
approximate the non-printable area. In your case I
would assume the Width would be 25 (1/4 of an inch).
Petzold's book has a good description on this issue.
FYI: ignore VisibleClipBounds when using the .Net
print preview code.
