Ok, the PDF needs to be edited/re-formatted so that each manual page is it's own PDF page. Then they can be printed in any manner desired; booklet, single/double sided etc. PDF game manuals are usually formatted like that - this one threw me off.
What's the trick for printing this up as a proper 2-sided booklet? That is, each manual page is half a letter size page, or 5.5" x 8.5", with cover followed by each page in correct page order and orientation. I only seem to be able to print 1-side with 2 page images per page. Same goes for South Gambit, but here the issue is a landscape oriented booklet... I know, burning questions..
