If you have a server that is an AD DC, you must at least run one with the print spooler if there is printing anywhere within AD, because that is the only way for AD to prune the spooler.

So you might not need to print on your DC, but your DC needs the spooler so that you can keep your printing system, healthy everywhere else... it's pretty much an indirect requirement.
