Function: DoPrintDialog
Parameters:
Description:
If the caller passes an empty PrintSettings object, DoPrintDialog creates
a new one, otherwise it validates the one provided by the caller.
It then invokes the Print dialog and checks for Cancel.
Note that the PrintSettings object is modified by this function.
