UPDATE: I am no longer maintaining this hack.  I haven't touched it in 2 years, and don't intend to.  My apologies to those who come here looking for help, but I just don't have the time to work on all the plugins and hacks that I have released over the years.  If someone else would like to take over development be my guest.

I really have begun to dig WP2PDF by theWalrus over at the www.thewalrus.info/.

Apart from a couple of small gripes from yours truly, I have found this software to be excellent and way more fun than allowed by law.  The only problem I could see was to really use it to its fullest you (the site author/admin) had to do alot of work, manually adding links here and there.

So I decided to throw together the following plugin, that currently gives your site visitors an easy to use interface to WP2PDF, allowing them and you to get more out of this great little piece of hackage.  Currently the interface is limited to creating a PDF by year, and creating one by month.  In the next version I plan to include by author and possibly by category, and probably someway to combine them, so if you want to have a PDF of all the posts that author a made in month b, under category ( c ) you could easily do that.

This plugin is pretty straightforward, all you need to do is edit the
$wp2pdfpath="/pdfstuff/wp2pdf";
bit and away you go.  Please note, I have my server set up to run without file extensions, so your $wp2pdfpath would be more like this:
$wp2pdfpath="/pdfstuff/wp2pdf.php";
Later.
