This is probably because https://github.com/pyppeteer/pyppeteer is unmaintained. We use that to get a headless chrome. I think the way forward would be to port this package to the alternative that is linked in that repository. If one of you has the time to do that, that would be great. I'm not sure how quickly I'll get around to it.

There is also a "export to PDF" that is built in to jupyterlab now, so maybe that is an option as well for you?
