Printer - PDF format: How can I change the header info and add page count on the footer? I like this Printer module on my Drupal 7 site. But, when it generates PDF, it contained breadcrumb and no page-count on the footer. Is there a way to add name of "Content type" and node "Title", instead of breadcrumb? I also would like to have the page-count number on the footer on every page. Is there a file that I can modify?

PS: I'm using mPDF third-party tool
The Print module uses a separate template for the print, email, and PDF versions of a page.  You would need to implement a hook_preprocess_print() to set up some addtional variables, and then duplicate print.tpl.php into your theme and use your new variables (and/or change the markup in the template).  The default template file is rather well documented, and explains what is possible.
