Bought a HP Envy 5000 two weeks ago. I only print pages with regular body text. No large bold headlines. From the included black ink cartridge I got about 15 pages. It caused some serious problems since I was on a deadline and was expecting to be able to print alot more. I managed to buy a new 304 black cartridge (not from the same store). It would print about 10 pages of the same black text before running out of ink. This is so bad I am lacking to find words for my disappointment. So how will HP help me?
