This plugin displays a small box underneath each article in which an email address can be entered. After sending the form a PDF will be created and sent to the entered email address.
The Plugin is completely free and easy to install.
Titles of articles in the PDF are linked with the articles in your blog
Increases the reach of your blog - it might be that created PDFs are forwarded to other people and that other people find your blog because of the linking.
Your blog or server don't need any special requirements
Created PDFs are sent by email - subject, sender and body of the email can be configured.
