Compatible HP W2120X 212X High-Yield Black Toner Cartridge | 13,000 Pages | Fits HP Color LaserJet Enterprise M554 M554dn M555 M555dn M555x MFP M578 M578c M578dn M578f M578z | Premium Ink & Toner

The W2120X is the high-yield version of the HP 212 black cartridge, rated for approximately 13,000 pages. The W2120A (212A) is the standard-yield version, rated for approximately 5,500 pages. Both work in the same HP printer models — the X delivers more than twice the output per cartridge, making it the better value for any moderate-to-high volume printing environment.

This is standard across HP's enterprise color toner lines. Black is the most heavily used color in typical business printing, so HP engineers black cartridges with higher toner capacity. In the HP 212X series, the black (W2120X) yields approximately 13,000 pages while the color cartridges (W2121X, W2122X, W2123X) yield approximately 10,000 pages each — all measured at 5% coverage per ISO/IEC 19798.

This cartridge is rated for approximately 13,000 pages at 5% coverage, which is the ISO/IEC 19798 industry standard for black toner. Actual yield will vary depending on print settings, document complexity, and average coverage per page. Business documents with standard text typically achieve yields close to or exceeding the rated amount.

Yes. Every Premium Ink & Toner cartridge undergoes pre-shipment testing for toner density, chip compatibility, and print quality to ensure output meets or exceeds OEM standards — deep black text, sharp graphics, and consistent page counts from first page to last.

No. Under US federal law (Magnuson-Moss Warranty Act), manufacturers cannot void your warranty simply because you use a compatible aftermarket cartridge. You are free to choose third-party toner without risking your printer coverage.
