I tried this.
Saved the tree as PDF.
Step1: Choose 5 pages in Width and 1 page in Height. (You need to try multiple times to findout which combination works for you using preview option)
Step 2: Once you identify the correct combination, export it to PDF, then print those PDF files. And put them all together either by Width or Height (as per your configuration in Step 1:)
I hope this solves your problem.
