I think Palemoon and Firefox has an option that lets you save a page as a pdf. Though I'm not entirely 100% sure.

You can also save a copy of an entire page by pressing cmd(or control) and the s button if you wanted to. But this won't let you expand the images inside a thread. They'll be in the default thumbnail display.

Another final and good option is making it yourself using Libre Office.

You can just put this thread's text inside a document, arrange the pictures, decorate if you want to and export it as a pdf. It surprisingly gives you a lot of options when making a pdf. Even giving you the option to embed external urls inside of it.
