Print or PDF all posts

I would like to use WordPress as a journal for my upcoming internship. However, before I do I want to make sure that I’ll be able to turn it into a nice looking document to give to my professors when I finish.

I’ve tried wp2pdf and I can’t get it to create more than 10 posts at a time (no matter what I do). Does anyone have another solution for printing or creating a semi-nice-looking file of all blog posts (even if there are 100+)? Kind of a “WordPress to book” sort of thing.
