Sheets("Invoice").Activate
ActiveWindow.SelectedSheets.PrintOut Copies:=4, Collate:=True

Sheets("SAD500").Activate
ActiveWindow.SelectedSheets.PrintOut Copies:=1, Collate:=True

'Print this sheet only if cell AX4=>2
If Sheets("SAD501-1").Range("AX4") >= 2 Then
Sheets("SAD501-1").Select
ActiveWindow.SelectedSheets.PrintOut Copies:=1, Collate:=True
End If

'Print this sheet only if cell AX4=3
If Sheets("SAD501-2").Range("AX4") = 3 Then
Sheets("SAD501-2").Activate
ActiveWindow.SelectedSheets.PrintOut Copies:=1, Collate:=True
End If

Sheets("Manhood").Activate
ActiveWindow.SelectedSheets.PrintOut Copies:=2, Collate:=True
Sheets("Invoice").Activate
