This is a problem in both the print preview and the print output (tested with Microsoft Print to PDF printer).

Simpler testcase: just paste the following into the address bar.
data:text/html,<input type="checkbox" id="myCheck"><script>document.getElementById("myCheck").indeterminate = true;</script>
