Quickie more printer stuff...
Downside: the thing just sucks down black ink. Of course, I'm printing Evil Geniuses posters at 11x17, and there's a lot of black in them.
Upside: Costco stocks the BCI-6BK in 4-packs.
Another upside: I'm already 30 posters in to the run. Did I mention this thing is seriously fast?
