When i press command P on a layout the PDF is completely empty

I open a new file, I do a square, I create a layout and center the square in it, but when I try to print it notting shows up.
Could you please help me to understand what is not working? I could not find such a trivial problem in the forum, and I never had this issue before trying on mac. Thanks!
