How to print to pdf on a Samsung Galaxy Tab 2 (7 )?

I am planning on bringing my tablet with me on vacation to purchase tickets for attractions with long line waits. Because I have to pick exact times, I am waiting to purchase them while on vacation and would like to make the purchase on my tablet. The hotel reception has said that I can send them a pdf and they will print the documents for me. I can't, however, figure out how to print to pdf from a website. On my laptops, I can click print and then just choose to save as a pdf. Does anyone know how to do this or can anyone recommend an app? Thanks!
