title: Crystal Reports 8.5 duplex printing
body: <p>I have Cristal Reports 8.5 I need to reset page number for every new group, and if group contains odd number of pages need to add blank page, if there is even number of pages nothing should be done just reset page numbers.
  I found many issues about this but nothing works as it should.
  There is Group Header 1 anf Group Footer 1, and report need to be printed on duplex printer.
  Thanks</p>
