Create a non-interactive copy of a webpage, possibly a PDF?

I have a search form that submits to the same page and it retrieves the results using an AJAX request.

This uses the POST method, and I'm trying to figure out a way to try and do something according to the fact that you have a button to open this page in a new window, to save the parameters and search results and allow them to be bookmarked somehow. but I can’t think how to do it.

Another main reason for this is that the search results contain links to the fact that the user clicks one and then clicks back all the form parameters are lost, I worked on this by opening the links in a new window.

Any help, advice and opinions would be greatly appreciated.
