This printer is intended to work only with cartridges that have new or reused HP electronic circuitry, and it uses dynamic security measures to block cartridges using modified or non-HP circuitry. Periodic firmware updates will maintain the effectiveness of these measures and block cartridges that previously worked. Reused HP electronic circuitry enables the use of reused, remanufactured, and refilled cartridges. More at: www.hp.com/learn/ds

Never run out: Based on plan usage, internet connection to eligible HP printer, valid payment method, email address, and delivery service in your geographic area.

Automatic delivery: Printers require direct connection to the internet for program participation. Internet access sold separately.

Savings claim (ink): Based on monthly subscription cost of HP Instant Ink 700-page plan without purchase of additional sets of pages compared to cost per page (CPP) to print ISO/IEC 24711 pages on most HP, A4 colour inkjet cartridge printers and MFPs. Comparative printers are priced at or below the most expensive HP Instant-Ink eligible printer in each country using local currency, as of September 2022. Sale prices not considered for this study. Average CPP per country used to determine percent savings versus CPP for HP Instant Ink. HP Ink Advantage printers, printers sold through contract, and other printers which only use XL cartridges excluded due to non-standard hardware & supplies model. Keypoint Intelligence October 2022 study commissioned by HP.

Savings claim (Mono Toner): Based on monthly subscription cost of HP Instant Ink monochrome toner service 1500-page plan without purchase of additional sets of pages compared to cost per page (CPP) to print ISO/IEC 24711 pages on most in-class, HP A4 monochrome laser printers and MFPs. Comparative printers are priced at or below the most expensive HP Instant Ink-eligible laser printer in each country using local currency, as of September 2022. Sale prices not considered for this study. Average CPP per country used to determine percent savings versus CPP for HP Instant Ink. HP printers that use original, standard-capacity, integrated toner cartridges (toner and drum in one cartridge) were included in the comparison. XL cartridges and printers sold through contract excluded due to non-standard hardware & supplies model. Keypoint Intelligence October 2022 study commissioned by HP.
