I have gone through the unsubscribe process since ordering ink about 8 times. You need to stop. Also, since I started using the HP ink cartridges, there are a lot of printing mishaps that cause me to print a second time. Using more ink than needed. Absolute last time I buy any HP product.
I purchased a 7740 printer. While I like the printer for my current needs, I'm disappointed that I cannot add it to my account for automatic shipments of ink. VERY DISAPPOINTED!
These ink cartridges are great. I have a workhorse OfficeJet Pro 8720 that handles most of my printing needs. I bought an Envy Inspire 7900 series to do photos. It's really good for photos but slow for everything else. Whereas, the OfficeJet Pro scans and prints fast. It just won't print on photo paper any more.
