wrong answer, Check out PC World Review of WF-4630:The real savings begin with the $42, 2,600-page black (1.6 cents per page) and $44, 2,000-page color tanks (2.2 cents per page, per color). With those more capacious supplies, you're paying a mere 8.2 cents for a four-color page. The cost of the LD product is a third to a forth the cost of the OEM cost reviewed. I have used LD products for over 20 years and these 786XLs I have used for over a year with excellent results. That's why I'm at the sight to re order again.
