Joliprint is not designed to work with search engine results list or homepages of sites and blogs. Joliprint only works with specific article urls. For example it won't work if you try it on freetech4teachers.com but will work with http://www.freetech4teachers.com/2011/04/its-april-15th-lets-learn-about-taxes.html. Take a look at a Joliprint rendered PDF of the link I just listed.
Applications for EducationIf you're in the habit of printing articles to give to your students to read try using Joliprint to convert those articles into a reader-friendly format while saving ink and paper at the same time.
