How to set Headless Chrome wait until the page is fully loaded before printing?

The command to use headless Chrome to print webpage as PDF is chrome --headless --disable-gpu --print-to-pdf https://www.chromestatus.com/. The wkhtmltopdf has a feature --window-status ready_to_print to do so.

I ask this question because when I print this webpage contains MathJax.js, it has an error as follows:

enter image description here

The page source of that webpage has the following lines related to mathjax

<script src="../scripts.js"></script>
<script src="../../MathJax/MathJax.js?config=TeX-AMS_SVG"></script>

I would like to ask if there is an option so that Headless Chrome will wait until the page is fully loaded before printing?

We can use two options to achieve this goal: --run-all-compositor-stages-before-draw and --virtual-time-budget=10000.
