Creating PDFs in AutoCAD

Hi,

I'm working at a office where we create drawings in AutoCAD and print thoose to PDF. We are trying to make a automated batch plot from a AutoLISP script. The only problem to make it fully automatic is that we don't know how to send a path to the Adobe PDF plotter.

Does anyone know any way that the Adobe PDF printer can recieve a path instead of the choosen outputfolder in the printer settings? With ActiveX, .NET or VBA.

We are working with Adobe Acrobat 9 Standard.
