A common task that developers attempt to do is print PDF files from code. Unfortunately, there is no simple and easy way of doing this. However, I found a work around using the Acrobat Type Library that can assist with this. It’s by no means the best solution, but will allow you to perform background printing:

        TotalPageCount = AcrobatPDFDoc.GetNumPages  
  
        'Perform a background print using Acrobat  
        ResultsBoolean = AcrobatDoc.PrintPagesSilent(0, TotalPageCount - 1, 0, False, True)  
  
        If ResultsBoolean = False Then  
            Throw New Exception("Acrobat returned a False value when attempting to print the pages in the background.")  
        Else  
            ReturnBoolean = True  
        End If  
    Catch ex As Exception
