Hi
While this may not answer your question, check Jack Hamilton web site at:
Lab-Useful: LabVIEW& Tips, Tricks and DownloadsHe has a Print to PDF.llb that: "Allows you to programmatically control the destination and filename for PDF printing in LabVIEW. You must use the report functions to print and have Adobe Acrobat writer installed on the machine - PDF writer does NOT need to be the default printer"
Eventhough it was made for LabVIEW 6.1 and Tested on Windows 2000 Professional, you might be able to figure out what's not working on your system by looking at Jack llb.
