How to send a block for printing?

Question

JavaScript

You need to print a certain block, the block is filled with JS.
There is an option to create a frame, fill it and print it, but this option is not suitable.
I need something different and more correct, because my work will be evaluated (this is not the whole work, but a small part of it)
Tell me how to implement this correctly?

Answer 1

The first option that came to mind: For everything except this block, set

@media print  {
    elements {
        display: none;
    }
}

Well, this block needs styles.
PS - Right now I thought of something, but I generally correctly understood the essence of the issue, or are you talking about something else?
