HP 851 Black Original Ink Cartridge

Prints laser-quality black text and graphics. This pigment-based ink was designed in conjunction with the HP proprietary color inks in the tri-color inkjet print cartridges compatible with your printer for crisp edges on text and around graphics.
HP Vivera Inks are the result of years of exhaustive testing. Ink chemists typically design up to 1000 prototype ink formulations that are subjected to hundreds of tests to see how the ink interacts with the cartridge, the printer, and the paper. More than 80 tests may be conducted on the print attributes of the ink and paper alone, to ensure the highest-quality results possible.
Print text documents and reports faster with the wider printhead on this genuine HP print cartridge. The print swath on the printhead is wider than on the HP 850 Black Inkjet Print Cartridge and HP 855 Tri-color Inkjet Print Cartridge and requires fewer passes across the paper and less waiting for your output.

HP Vivera Inks are pure, and free of harmful contaminants, ensuring optimal reliability and performance. The ink formulations undergo more than 40 tests to meet HP specifications. HP Vivera Inks are produced using advanced filtration systems and clean room technologies to maintain a consistently high level of purity for high-quality results time after time.
Advanced inkjet cartridge technology ensures excellent results every time—from business presentations to important text documents.
Genuine proprietary HP Vivera Ink, specially-formulated HP papers, and HP printer software are designed as an integrated printing system. Their performance is optimized when used together to deliver exceptional print quality, time and time again.
