Yes, although you'd get a different pdf for each web page. I just looked at a random book and the main page was a set of links for a new page to each tablet of Gilgamesh. So, click on one of those and you can get the entire tablet as a pdf, but then you'd need to do the same for each of the 11 tablets.

This beats the heck out of my previous process: view an article from a web page on the macbook, print/save to pdf in a specific folder for transferring to the edge, periodically put those files on an SD card and load them onto the edge. Now, it's just browse to a page on the LCD side and click the "send to e-reader" button. It shows up on the e-ink side for reading, and if you want to save it to the library, you can click the add to library icon. If you want to just read it but not save it (helpful if you're outside and just want to be able to see it better) then no need to do anything with the file. It will "go away" the next time you open a document on the e-ink side.
