I've been dealing with HP printers and inks for many, many years and suddenly I realized that black ink runs out fast, even though my computer printer says it still does there is a lot of ink in the cartridge. Also, my recently purchased color ink printer doesn't produce the stunning color prints I'm used to. I love my HP printer and have always bought HP printers. the problem is not with them. It happened while I was preparing a letter to the Senator - good thing I had a new black ink cartridge again - but having just installed it, I'm wondering how long it's really going to last. I've been using HP inks for as long as I can remember. This has never been a problem for me, and being an avid PC typist I've used a lot more ink from their cartridges. I have a feeling we are being deceived.
