Hi Salvatore,

re:

For that case I would recommend turning off "Center on page", that will make MoI use 0,0,0 as the page origin and you can move your objects to position them where you want to control where they will be printed at.

You can draw a rectangle starting at 0,0 and with your page width and height if you want a visual guide to see what area in model space is going to map to the output page.
