convert mail merge documents to individual pdf docs

I created a mail merge using Word 2010.  It is several documents combined into one large Word file with section breaks.  It is many pages long.

I need to convert it into individual pdf documents.  I have used the vba code bleow with pdf creator with some success.  I now need to do the same thing with E-Copy 5.3

Sub SplitMergeLetterToPrinter()

    Dim Letters As Long, Counter As Long

    Letters = ActiveDocument.Sections.Count

    'MsgBox "Sections counted = " & Letters

    Counter = 1

    While Counter < Letters

        ActiveDocument.PrintOut Background:=False, Range:=wdPrintFromTo, _

            From:="s" & Format(Counter), To:="s" & Format(Counter)

        Counter = Counter + 1

    Wend

End Sub
