Print is cheaper than ever, thanks to countless print-on-demand services. You don't need to worry about over or under production, managing stock, or even fulfilling orders.
You could start your own monthly print journal, say The New World Journal of Slashdotic Trolldontia, and produce it for less than the cost of a domain and hosting. IIRC, with Amazon, it won't cost you a penny to have print copies of your journal (including an ISBN) available for purchase.
Junk, super-low-cost, hosting and domain will set you back $45/year.
what do the costs of a print journal work out to per paper carried? Now compare the cost of online publication.
Looking only at distribution costs, not production costs (which should be identical), that works out to $0.00 vs $45.00, for any reasonable number of articles per journal.
While readers would pay more for the print version, they could still get the entire journal, in print, for less than the cost of a single article, in PDF, from SpringerLink.
