Print PDF from Powerpoint with VBA and add existing PDF

Hi,

I use a VBA macro to create a PDF from a PowerPoint Presentation. I also want to add existing PDF documents to this PDF-File. Currently I can add PS-Files to the Printjob and merge them befor conversion, but this isn't the best way cause of lower quality. I wish that i can create the PDF-file from Powerpoint and add / merge an exisiting PDF file, without new convertation of this exisitng file.

Is there any chance to realize this with the VB interface?

Hope my english is good enough to explain the problem.

 

thanks
