If you want to print an image of that size you’ll need to keep it as a vector image instead of rasterizing it.

You can use the browser’s developer tools to inspect the SVG and copy its outerHTML:

Save the copied markup to a new text file and give it an .svg extension. Afterwards you’ll likely need to edit the viewBox attribute until all of the graph is within the visible bounds.

Whatever service you use for printing may be able to handle SVGs directly, but just to be safe you’ll likely want to convert it to a PDF.

Thank you for solution! It is great - however there is no portrait pictures within - the next question is - how to add pictures?

You will likely have to inline all the images. One thing you can do is to run the following snippet in the developer console to turn all image URLs into data URLs:

await Promise.all([...$$("image")].map(async n => new Promise(async(resolve, reject) => {
    const url = n.getAttribute("href");
    if(!url) return resolve(false);
    const reader = new FileReader();
    reader.addEventListener("load", () => {
        n.setAttribute("href", reader.result);
        resolve(true);
    });
    reader.readAsDataURL(await fetch(url).then(r => r.blob()));
})))

Unfortunately you’ll end up with a 50+ MB document. Since most of these images are placeholders it would probably be wise to extend the script above to declare these as <defs> and then replace the actual images with <use> references.
