The page yield is based on an industry standard to calculate but does not guarantee that customers will experience the stated yield in actual use. Actual cartridge page yields are affected by printer used, types of pages printed [like photo vs letter], frequency of printing, print settings and other factors.

HP participated in, supported the development of, and adopted the ISO/IEC 24711 standard for determining inkjet printer page yields. HP also participated in, supported the development of, and adopted the ISO/IEC 19752 and ISO/IEC 19798 standards for determining monochrome and color laser printer page yields.
