In the future you could consider finding an online 3rd party printer service, I found something randomly here in france, a few years ago, for people who write their books and want them available in print copies. They basically produce the books on the fly and send them to the buyer, they take a fee, and the authors define themselves how many € they want to get on top of that per book (they can define 0 if they don't want to make a profit out of it and make it cheaper), which then defines the book price (it depends on the content, no of pages, images or not, glossy or not etc). It can be expensive though for a glossy type of prints, it's not comparable to a mass production, but if some people are into it, why not. The service I'm mentionning costs nothing before the cut they take on the book price, so if it ever exists in the US for example, it could be another option.
I think the reaper manual guide still exists in print format, maybe they are using such a service
