I changed the page orientation to landscape and that removed the truncation. I am not sure why it is not using the "shrink to fit" but for the purposes of this exercise I can live with this solution.
If I click Print Preview I can view all pages and then if I select the Print Icon I get a PDF file containing all pages. This is so bizarre.
So to recap
File > Print > Adobe PDF Printer only creates 1 page
File > Print Preview > Print Document (Alt +P) > Print >Adobe PDF Printer creates 7 pages
I guess this would be a good time to call support to see what they have to say on this topic.
