Very helpful in finding the right printer ink for my HP Officejet Pro 8720. Store manager saw I was looking up the ink from the book. He came over asked which printer I own and immediately handed me the right cartridges.
Why the color cartridges are empty is nuts. I virtually never print in color. And it wont print in black when the color cartridges are empty. Total RIP off
The combination pack of ink has worked well for me. I am not sure whether it is because I always used the HP brand ink cartridges vs. refilled cartridges or if the HP 6700 printer itself is very durable. I print more documents in black ink only so the high yield black ink and standard yield color cartridges combination pack is most useful for me.
