Hi Chris and thanks for the answer!

Yes, I did it. I copied the entire example you mentioned (that I've
found on the page) and pasted it in the app.js. So I added it to the
var print_preview as you said. I can choose my new layout from the
drop down menu I named "A4-verticale" (so it should be correctly
loaded) but the generated PDF doesn't contain the legend: only the
title, map, scale bar, title legend appear, and a rectangle for legend
frame, but the legend is not there.
I use millimeters (mm) as units so I thought the problem was there
(perhaps my error on positioning the objects) but the same behaviour I
encountered in my local demo site with demo data (after modifying the
app.js for the new layout like above) in which I didn't modify any
units.

This is my settings in app.js:

 {
   label: 'A4-verticale',
   orientation: 'portrait',
   page: 'a4',
   units: 'mm',
   elements: [
       {
           type: 'text',
           size: 18, fontStyle: 'bold',
           x: 10, y: 15, text: '{{title}}'
       },
       {
           type: 'map',
           x: 10, y: 18.5,
           width: 160, height: 160
       },
       {
           type: 'rect',
           x: 10, y: 18.5,
           width: 160, height: 160,
           strokeWidth: .1
       },
       {
           type: 'text',
           x: 10, y: 185, text: 'Stampato il {{day}}/{{month}}/{{year}}'
       },
       {
           type: 'text',
           x: 10, y: 190,
           text: 'Legenda',
       },
       {
           type: 'legend',
           x: 10, y: 193
       },
       {
           type: 'rect',
           x: 10, y: 193,
           width: 100, height: 100,
           strokeWidth: .1
       }

   ]
 }

and then:

  var print_preview = app.add(gm3.components.PrintModal, 'print-preview', {
    layouts: custom_layouts
  });
