Saying OEM HP printer cartridges are more reliable than compatible cartridges isn’t an opinion — it’s a fact!

The color study compared the original HP cartridges with six non-HP brand cartridges. The monochrome study compared original HP black toner cartridges with seven non-HP brand cartridges.
The study found that 98% of non-OEM toner cartridges have some type of reliability issue, like low print quality, premature failure, or dead-on-arrival

The Science and Technology Behind HP LaserJet 42A (Q5942A) Cartridge
LaserJet printing is one of the most energy and material-efficient types of digital printing to date.
The technology uses a set of cylinders and the power of positive and negative charges to transfer powdery toner particles to paper. Toner is then heated and fused to the paper. The result is the joy of holding slightly warm bunches of freshly-printed documents.
HP 42A Black Original LaserJet toner cartridge is a part of the JetIntelligence series – it has a few smart features that make it more cost-efficient, better at producing crisp prints, and easier to use and install.
The technology includes:
Proprietary toner formulas for that deep, rich black of original HP toner cartridges that never gets clogged or messy
Page maximizer technology for high yield printing even with compact cartridges
Print gauge technology that gives you all the information you need to track the health and life cycle of your toner as well as how much toner you have left
Auto seal removal for easier cartridge replacement and safer transport
Anti-fraud technology that helps customers recognize counterfeits and make sure they use Original HP toner cartridges
What Makes Q5942A HP 42A Environmentally Friendly?
HP is committed to greener business practices. All original HP toner cartridges produced in recent years are considered more eco-friendly than the competition.
By 2022, Hewlett-Packard has recycled more than 4.9 billion printer cartridges through their recycling program. In addition, the company kept 4.7 billion plastic bottles and 114 million plastic hangers out of landfills.
HP used the recycled material to manufacture new ink and toner cartridges. Their manufacturing model makes them one of the industry leaders when it comes to environmental efforts.
In fact, 100% of HP LaserJet cartridges are made out of up to 75% recycled content, including the 42A. In addition, the packaging for this toner cartridge is made up of 81% recycled materials.
This standard-yield toner cartridge is designed for an already material-efficient technology – HP 42A toner yield is approximately 10,000 pages per cartridge, which is a fairly efficient output.
Compared to most other LaserJet printer cartridges, HP 42A technology has greatly reduced the level of emissions. This will make an office space equipped with HP LaserJet printers less polluted with volatile organic compounds.
