Damn, I tried a lot of solutions before trying yours since i finally wanted to try a client side solution (i.e. in javascript)

Since the css i am using is kinda simple, i tried half a dozen of solutions.

Clearly for me, wkhtmltopdf is the greatest solution. I wish i had found a way to do this on the client side but at least i get exactly the same output as my html.

Thx for pointing me this out.
Also thx to anyone contributing to the thread :)

cheers
