wicked_pdf

Finally a pdf solution that works great and is fairly easy to set up. It uses simple html as a template for the pdf rendering.

First download and install wkhtmltopdf program. I used this osx version:
wkhtmltopdf

Then I had to change the name of the binary to just wkhtmltopdf and put it in the search path. In my case /bin

The wicked_pdf plugin uses the which command to locate it.

Then follow the simple instructions at wicked_pdf github page.
