How can I snap to print page borders? (Image example provided)

Hello!

I'm trying to create a printing layout for myself, but I'm having trouble creating it. I want a specific distance between the viewport border and the print page border. Since I can't snap to the edge of the print page, I don't know howto to achieve this.

Could someone please tell me how to snap to the edge of the print page, or set exact distance between edge of paper and viewport?

I added image as an example
