I received the expensive color cartridges and they will not go into my printer… I am still trying as I need to print and these are the correct size according to the list.. I have a HP Office Jet Pro 7740.
The ink cartridges work great, and for that I would give them five stars. But there are a couple issues that reduced my rating. 1) They are WAY overpriced. 2) If I use other brands of cartridges that are made for this printer they don't work due to the printer being set up to not accept anything but HP cartridges. I feel these are not mutually exclusive, and that HP is doing this on purpose so they can charge a lot more for the cartridges. And that just ain't cool man.
Foolishly I bought cheaper cartridges from a firm which refills and sells the product at a much cheaper price. While they worked OK for a while I started getting poor quality prints and had to clean the heads very frequently. Never had this problem before when I used the HP ink cartridges. Live and learn, I'm back to using the more reliable product.
