Thank you! I could not make it work at first but the solution was commented out further down in the default project.ptx file.
I added the deploy-dir="pdf" attribute to the print target, and I also added the attribute output-filename="main.pdf". After that, I got a working link to the pdf file. Without output-filename the link just pointed to the pdf folder, not the file.
Note: after doing the above, I got a link to the pdf, but no link to the web version. Adding the attribute deploy-dir="web" to the "web" target, created a link to the web version. So now I have both links. :-)
Cheers,
Fred
