If you need to print out an entire website, here is a little trick. You’ll need the full version of Acrobat though. I did this using Acrobat X Pro, but I believe this works all the way back to Acrobat 8.x.

Go to File | Create | “PDF from Web Page…”. In the window that pops up, type in the url of the site you wish to traverse. The trick here is to click the odd little button on the left, “Capture Multiple Level”. The window will expand to expose a few more options. Select the “Get entire site” option and click the Create button. There is a warning that you will create gargantuan files that will grind your computer to a halt, but ignore it. I converted an entire 20-page site and the resulting PDF was under 900k.

Now you can open the PDF, email it, or print like any other document.
