how to Print Autocad Files From Excel Vba

plase... anbody?
If I have a dwg # in a sheet cell, how can I print that dwg. from excel vba.
This is as far as I got: (I need help with the last 3 lines)

Sub print_dwg_from_excel()
A = ActiveWindow.ActiveCell.Value
B = Dir("c:\AUTOCAD\" & A")
C = "c:\AUTOCAD\" & B
Set fs = CreateObject("SCRIPTING.FILESYSTEMOBJECT")
Set f = fs.GetFile(C)
s = f.PrintOut
End Sub
