HP 776 1-liter Matte Black DesignJet Ink Cartridge (1XB12A)

HP part 1XB12A is the 1-liter Matte Black tank in the HP 776 range — the largest single volume among the genuine HP cartridges we stock.

Which printers take this part

HP lists 1XB12A for the DesignJet Z9⁺ series — the 24-in, the 44-in, the Z9⁺dr and the Z9⁺ Pro, the platform behind PSE’s Education Print Center Pro 64. It is listed for that series only; if your badge reads Z6, this is not your part — the matte black we list for a Z6 is the 300 ml HP 746 cartridge, P2V83A. The 776 parts for this platform are listed together on the Z9⁺ ink page.

What Matte Black does here

Matte Black is typically the ink of choice when printing on uncoated or matte media, where it produces deeper blacks than Photo Black on those surfaces. The Z9⁺ holds both blacks, and matte black is the one used on uncoated and matte stock.

Size and cost per milliliter

One liter costs less per milliliter than three 300 ml HP 746 tanks of the same color, and holds 100 ml more — the lowest ink cost per milliliter of any genuine HP cartridge we stock. To compare sizes, read this page’s price against the 300 ml page for part P2V83A.

Don’t order this by mistake

The number below, 1XB11A, is this platform’s other black — Photo Black, for coated and glossy stock — not a second matte tank and not a substitute for this one. The other easy slip is size rather than color. P2V83A is the same matte black role in a 300 ml HP 746 tank, so a part number recalled from an older order can arrive as 300 ml when a liter was budgeted — read the range and the volume off the tank, not just the color word.
