I have found some libraries or web services in PHP that does the job. The problem is that the conversion is done when the page is fully loaded, I would like to convert the page to PDF after some content dynamically added via AJAX in onload event.
Thank you very much, Omar
Wow, thank you everyone I didn’t know that this is comunity is so active. To answer Beepcake about the project:
When the page loads the app retrieves, from more than 40 servers, biological information via AJAX request, then a unique view is displayed where you can manipulate the graphic with many options.
So, the cool thing will be to print when the user makes his own version of the graphic. I think that the best solution is to POST the entire HTML with document.getElementsByTagName(‘html’)[0].innerHTML as RoBorg has said and then generate the PDF with a library such as dompdf
