*SpencerLab Sept 2021 study of printer inks sold in North America commissioned by HP for on-average performance of 16 brands of non-HP refill, remanufactured, and imitation cartridges vs. Original HP Ink SKUs 952XL, 63XL, 902XL, 950XL, 951XL. To account for reliability-driven supplies issues, defective and failed cartridges were included in the page yield calculations. Consequently, the reported page yield numbers are not based on ISO/IEC 24711 standard methodology, as it requires defective supplies be excluded from page yield calculation.
