My family has a couple of hp printers, and that is why we are always looking to by hp ink cartridges. I prefer to purchase the package that contains the color and black and white ink cartridges because I find that it is cheaper. You can purchase the ink cartridges online which can make life a lot easier for you. Even if the ink cartridge is hard to find in the store, you can easily find it online. That is why I like the HP printers. I never have a problem finding the cartridge I need when I search for them online.
