The Hewlett-Packard (HP) Ink Program, called HP Instant Ink, is a subscription service that automatically delivers ink cartridges to your door when your printer detects ink is running low. It allows customers to choose a monthly plan based on how many pages they print, not the amount of ink used, starting as low as $1.79 per month. With Instant Ink, each page costs the same regardless of color or black and white, and the subscription includes free cartridge recycling with prepaid mailers. The program supports most HP printers made in the last 5 years with Wi-Fi, and customers can change or cancel their plan at any time[1][2][3].

Key details include:
– Ink is shipped automatically as needed, not on a fixed monthly schedule, based on printer monitoring ink levels[1].
– Plans charge a fixed monthly fee for a set number of pages; extra pages cost $1.50 per 10-15 pages[1][2].
– Subscription plans help users save up to 50% on ink costs compared to buying cartridges outright[1][3].
– There is a strong recycling initiative through HP Planet Partners, with over 962 million cartridges recycled so far[1][3].
– No long-term contracts; customers can change their plan or cancel anytime (though cancellation may have specific steps)[2].
– To use Instant Ink, printers must be connected to the internet[3].

The program aims to reduce the inconvenience of running out of ink unexpectedly and offers a more predictable cost model for printing, especially suited for home offices and regular printer users[4].
