Genuine OEM HP PhotoSmart 6512 e-All-in-One - B211a Ink and Supplies
HP 564 black, cyan, magenta and yellow cartridges work separately in the Photosmart 6512 B211a. The three-color pack groups only cyan, magenta and yellow, so ordering the color set does not commit you to another black cartridge.
At Toner Buzz, genuine HP 564 ink for the 6512 B211a includes standard singles, the color three-pack, and XL choices for black and cyan. Select a single for the exact ink that is low, the pack when all three colors need changing, or XL when black or cyan needs more capacity.
