You have to use VBA;
In a cell (somewhere, say Z1), do (from the Menu, Insert
Symbol, Click (once you find it) the Circled C.. - Click on the Insert
button.
Now with Z1 = C (copyright sign)
Go to VBE - This Workbook,
Private Sub Workbook_BeforePrint(Cancel As Boolean)
ActiveSheet.PageSetup.LeftHeader = Sheets("Sheet1").Range("z1")
End Sub
Hope that helps,,
