Navigate on a computer to the web interface Open the conversation that you want to print Scroll up until the entire conversation is loaded Open the Javascript console 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.
