From my addon to Advanced Layout Designer

Hi!

I've a big problem:

-I created a layout with ALD;

-i wrote an add-on

now my add-on has to print a layout, the layout that I created, passing to it values/variables.

How can I do it from my add-on code??

Please help me!

PS: I think it's possible because i've seen another add-on that do it.

Thanks!

Giuseppe
