Ask HN: Printing every post from a blog

There are a few blogs that I recently started subscribing to and I'd like to go back and read everything that's been written since the sites began. I'd like to be able to print them so that I can mark them up as I go through them. The problem is that some have several years worth of posts and I don't see a way to do it without going page by page through the archives and clicking Print on each one. Is there an easy way to gather all the old posts so that I can hit Print once and be done with it?
