Notes:
If you are calling RemoveAllWatermarks from within the printing procedure (while in the PrepareReport event of the PrintPreview control) to remove the watermarks from certain page and ahead, call it before the Printer.NewPage that adds that page.
Also, if you are calling RemoveAllWatermarks from within the printing procedure, add the watermarks by calling AddWatermark method inside the printing procedure too.
