A:Answer You won't be able to "pre-order" ink through the Instant Ink program. However, you can get them from Staples or Best Buy. You'll want to get the high-capacity XL cartridges. I'd get the 916XL for the black-that's rated at 1500 pages, so you'll probably need five of those. For the colors, it depends on how much color you have on the pages, but you'll need several sets of those as well.
