Print from mobile device goes wrong

Hello, first of all thanks for this great plugin!

I am developing a website where I want to use a Print O Matic. Unfortunately there are some problems. I made this test page to explain what happens

As you can see it works perfectly from my laptop. The body is printed neatly. Printing specific targets also works well:

Print all blocks from laptop
Print block 1 from laptop
Print block 2 from laptop

But unfortunately not from my mobile device. When I print a page from my mobile phone, the entire page including header, menu, sidebar and footer is printed. Printing specific targets also does not work from mobile device. Even then the entire page (including header, menu, sidebar and footer) is printed:

Print from mobile device

Please, can anybody help me to solve it?

Technical information:
Theme: Divi (Elegant Themes)
Editor: Gutenberg
Print O Matic: 2.1.3
Wordpress: 5.9.2
PHP: 7.4 (I also tested with 8.0)
