Out of curiosity, what's it cost you to print off a PDF?
It depends on the page count and paper stock, but about $10.00 to $20.00 on average for 200-ish, double-sided, pages with clear mylar covers sheets and spiral binding. The last thing that I had printed and bound in this manner (Labyrinth Lord) had full color covers with the mylar overlays, was spiral bound with wire, and cost $13.00
Do you do it in full color/high quality or do you scale down?
Again, it depends on the book, really. I typically only print in greyscale, save for covers and/or maps, as color rarely has much
utility outside of those areas in RPG books. In most cases, I can print entirely in black and white and lose no utility. I do always print in
extremely high resolution, regardless of whether I print in color or not.
My understanding, though, is that it costs almost as much to print a PDF yourself as it does to buy the book in the first place.
Not at all. You just have to go to a print shop with reasonable rates (sadly, they're not as common as they could be). A cost of $10 to $20 is less than about one third to one half of what a regular RPG book costs these days. When I factor in the PDF purchase price, I'm typically looking at something close to the price for a book off of the shelf, though occassionally about $10.00 less.
That said. . .
The
real advantage to PDF books is, IME, that if your printed book gets damaged, you can always print a new copy. If you only have a hardcopy of a book and it gets fouled with water, soda, or
fire (I've had it happen) -- or if it is lost or stolen -- you're pretty much 100% screwed on recovery each and every time.
Also, though it may sound like a small thing, being able to open a reference book to Page X during game play and have it
stay open to Page X is a thing of beauty.
