Ink level warnings and indicators provide estimates for planning purposes only. So if you are not a frequent printer, go with the regular cartridges. Our advice is that if you print often, go with XL. They will be able to print at least double the pages of a regular cartridge. XL (Extra Large) cartridges cost more but do provide better value in the long run. HP recommends that you use original HP ink cartridges. As you turn on the device and get ready to use it, an initialization sequence localizes it to the country associated with the ink cartridges you installed. When you unbox a new HP inkjet printer and set it up, you install a set of ink tanks that ship with the printer. Unlike other inkjet manufacturers, HP often designs its inkjet hardware to use country-specific consumables. Cartridges are not compatible between different brands, and often not within the same brand. Make sure you purchase the right ink cartridges for your specific printer and printer region or have your old ones refilled.
