Ages ago I created my own project in Java that enables me to export my entire blog (or parts of it) to PDF. Not very useful for my personal blog off course, but for the two blogs I have created for my kids it is my master plan to sometime have a book created. Who knows, in 50 years if they are able to view the content of the B2Evolution blog, but paper will for sure last that long.
My project is hosted by Google Code, http://code.google.com/p/b2evolution-to-pdf/ – free for everyone to use with the limitations that the third party libraries have.
Main purpose of publishing it to Google Code is to have a backup of the code, not just store it on my Lenovo T60 laptop which is…7 years old now? Second, it might be that someone out there might have the same need as me, and maybe my effort could save them time.
