So in Revit 2013 I noticed a small little change to the print setup dialog box.  This change is minor and doesn’t really affect any options but will be nice for clarification.  In 2012 and earlier when you changed the Zoom option to “Fit to page” the % size dialog didn’t change.  This could cause confusion where users thought it would fit to page but at 100% of the view.  Now in 2013 when you change to “Fit to page” the % size option disappears.  Not a big deal but I have had questions in the past on this and hopefully it will make things more clear.
