Log Message:
-----------
Howard Hoagland. 1. Get the dpi that the print driver of the selected printer picked (examples 300 or 600 or 1200 dpi). 2. Added comment line for centering Legal image on Letter paper. 3. For Legal image on Legal paper (not forcing paper change), bumped the image to the right slightly so that the vertical lines on the left edge of the image won't be chopped off on the left.
