You may have all of your magnification parameters set to 100 %, but  in
all reality, the thing that is making your life difficult is nowhere to
be found in either Cell or notebook Options.  Do the following:

1) With your problematic notebook selected, click on the front end  menu
command sequence:

	Format -> Edit Style Sheet...

2) Click on "Import Private Copy" when a dialog box pops up.

3) Open the cell groups 

	Styles for Input/Output


4) Unformat the cell prototype for


You'll see this setting:


This is what's causing your discrepancy.  This style sheet setting  is
inherited by all Graphics cells when the Printout environment is used.

When you size your graphics, they get reduced by 20 % when printed. If
you want them to appear as 100 %, change the magnification value to
1.0, and you should see a good matchup.
