I recently bought a new Printer from HP. After having the ink cartridge's refilled an bringing them home and trying to get them to work in my printer, I then discovered that they will not work in the printer! I was outraged and called HP with the complaint. After several weeks of hearing nothing an HP REP called and offered my 2 printer cartridge's to shut me up. I said to the guy, YOU ARE GREEDY, and take it to a new height in the definition! Keep your cartridge's and I will just go to site jabber and post a SHAME ON YOU!
