How to convert slide deck to pdf on Mac?

[hajime]

Hello, I am watching some slides via slide deck on a web browser. What is the best way to convert all the slides into a single pdf file for printing? Thanks.

Do you have access to the source material? Or can you reach out to the author/presenter and ask for a pdf version? Otherwise, it's a little painful: screenshot the slides, then export as pdf from preview.

I don't have the source. Yes, it seems to be a pain to do it page by page.

Do you know how to print in codelabs? I tried to print print from Preview but it only shows the top portion of the page even the page is very long.
