Comments about EPSON� 676 XL Pro High-Capacity Ink Cartridge; Black:
Guess it depends on how much printing you do but this black cartridge lasts longer than the other colors. I do have one on the shelf and one in the printer. I like this printer Epson WP4530. It does a good job of turning over the page and the ink doesn't bleed through. (I had this problem awhile ago when printers didn't print on both sides - you, the operator, had to turn the page. What a mess when it bled through!) Be sure to check the expiration date - I usually use mine up before it expires.
