The HP 923e Black EvoMore Ink Cartridge is HP's most sustainable black-ink option yet, promising up to 1000 pages per cartridge while keeping 2300 metric tons of ocean plastic out of landfills. I spent three weeks running it through an OfficeJet Pro 8135e to see if the eco-credentials hold up under real-world printing conditions, or if it's mostly greenwashing.
I spent a week running the HP 936 CMY ink cartridges through daily print jobs on an OfficeJet Pro 9125e to see if the 800-page yield claim holds up in real-world conditions. Short answer: mostly yes, with a few caveats worth knowing before you click buy.
The HP 61XL Black High-Yield Ink Cartridge delivers reliable, streak-free printing across a wide range of HP DeskJet, ENVY, and OfficeJet printers. With an approximate 360-page yield, it's a practical upgrade over standard-capacity options — though cheaper third-party alternatives and OEM remanufactured cartridges deserve a closer look before you commit.
