Not a print to WordPress plugin as such, but this will import the PDF text into the editor.
https://wordpress.org/plugins/aspose-pdf-importer/
Or use a custom PHP class such as:
http://www.phpclasses.org/package/9423-PHP-Convert-PDF-to-HTML-using-Poppler.html
which will convert the pdf to html, hopefully with styles. You’d need to create a page template for the html if you want to change the entire layout of your page to reflect the PDF. Though as you want them to be blog posts you’re possibly stuck to having to use the editor, so trying to match the layout might not be ideal and the first suggestion, using a plugin to get the text, might be your best option without some clever custom coding.
I know this isn’t exactly what you’re looking for I hope it’s of some help!
