I've written a little javascript bookmarklet that solves this problem:

Create a new bookmark in your browser called "Hide Internal Comments (Zendesk)" and then paste the javascript below into the URL field.

javascript:(function(){let comments = document.getElementsByClassName('internal_note');for (let x = 0; x < comments.length; x++) {let comment = comments[x].parentElement.parentElement;comment.style.display = 'none'}})();

After you open a printer-friendly ticket, you can click on your new bookmarklet to hide all internal comments.
