How to print an entire conversation from Google Messages

Question

I need to print out an entire text conversation that I had on Messages on my phone to submit it to someone's supervisor. When I try to print it on the website it only gives a screenshot of what I am looking it.

Answer 1

1. Navigate on a computer to the web interface
2. Open the conversation that you want to print
3. Scroll up until the entire conversation is loaded
4. Open the Javascript console
5. Copy and paste the Javascript below into the console and hit enter

(function() {
    var originalContents = document.body.innerHTML;
    var printReport= document.querySelector("mws-messages-list");
    document.body.innerHTML = printReport.innerHTML;
    document.body.style.display = 'block';
    document.body.style.overflow = 'visible';
    window.print();
    document.body.innerHTML = originalContents;
}())

Thank you AbhiNickz for this answer as a starting point.

Google messages updated their divs:

(function() {
    var originalContents = document.body.innerHTML;
    var printReport= document.querySelector("body > mw-app > mw-bootstrap > div > main > mw-main-container > div > mw-conversation-container > div > div > div > mws-messages-list")
    document.body.innerHTML = printReport.innerHTML;
    document.body.style.display = 'block';
    document.body.style.overflow = 'visible';
    window.print();
    document.body.innerHTML = originalContents;
}())
