Creating PDF's from articles comes with many problems, getting them to look correct is hard just because the styling of it is very different then a normal article. Using print css can be a better solution and I am sure there are extensions for that sort of thing.

This is just a suggestion though, from personal experience, below is how I added PDF views in Joomla Sites.
There is a way to "re add" the pdf views from a programming perspective.

This is for 2.5 however I have used it in up to 3.2 as well (not sure on 3.3).
It may be difficult to do but with an article override as well it is possible to re add the "pdf" button as well.

This should allow you to add the extra button in all views you need. It does require some coding experience but the guides should help with that.
