Ruth,

You can use a RunApp macro to open the Word document.  The Command Line
argument will be something like this...
 "C:\Program Files\Microsoft Office\...\Winword.exe"
"D:\YourFolder\YourDoc.doc"

However, as far as I know you can't make this print via a macro.  You
can use Office Automation code to print the Word document.  I think
something like this...
   Dim WordObj As Object
   Set WordObj = CreateObject("Word.Application­")
   WordObj.Documents.Open "C:\YourFolder\YourFile.doc"
   WordObj.PrintOut Background:=False
   WordObj.Quit False
   Set WordObj = Nothing

You would need to set a Reference to the Word Object Library.  More
