Use Aspose as a printer driver

Hi My employers have provided me a licensed copy of latest version of Aspose.Total. One of our requirements is to use this to replace the use of an old AMYUNI printer driver for generating PDF output programmatically from MS Word, MS Internet Controls (SHDocVW), MS Excel, MS Visio. I see the Aspose.Cells.Workbook.Save and Aspose.Words.Document.Save have PDF options. Can you advise what we may be able to do with Visio and SHDocVW please? Perhaps there is a method to use Aspose library as a pdf printer driver? thanks for your attention. Jeff
