The HP OfficeJet Pro 9015e's XL black cartridge outlasts the color cartridges by 400 pages

The 9015e runs HP’s 962 series ink — four separate cartridges for black, cyan, magenta, and yellow. What’s interesting is the yield gap: the 962XL black cartridge hits up to 2,000 pages while each color XL cartridge taps out at 1,600. That’s not huge, but it means you’ll replace color cartridges about 25% more often. Standard-yield 962 cartridges are available too, but the XL economics are better for anyone printing at moderate volume.
