I bought a new HP All-In-One Inkjet printer. New HP printers come with HP ink cartridges that are filled with "trial size" volume of ink. I purchased this ink for when the original cartridges run dry. Have not needed these yet. One time in the past I made the mistake of ordering inexpensive "compatible" cartridges. One of them leaked after awhile requiring a replacement of the printer. I will now only buy the HP cartridges - Lesson learned!
