title: Codeigniter how to create PDF
body: <p>I'm going to create an invoice system, I am preparing for that now.
  I'm gonna use Codeigniter.
  The thing is that I want to create invoice in PDF so I can send it through email.</p>
  
  <p>What is your guys advice?
  I was thinking of HTML to PDF conversion,
  Or Show the invoice on screen and install a pdf printer (when you hit print and you choose to print to a PDF file)
  Or create a word document and connect to the MySQL server I think with odbc.</p>
  
  <p>Any of you guys have experience with this?</p>
