Autoprint with a pdf watermark

Hello, I would like to print automatically a file with a watermark by a pdf file. The watermark is ok using "Action after saving" and "WatermarkToPDF.vbs", if I save and open the final pdf file is perfect. But when I set "Print after saving" the file is printed without the watermark. Does anyone know how can I set the watermark before the automatically printing action??

Thanks in advance!!
