      wkhtmltopdf and wkhtmltoimage are open source (LGPL) command line tools
      to render HTML into PDF and various image formats using the QT Webkit
      rendering engine. These run entirely "headless" and do not require a
      display or display service.

      There is also a C library, if you're into that kind of thing.
