Now, you have an answer for your whiners. Unless, that is, you are the culprit that dreamed up this scheme!!! Don't you realize that you are creating quite a market for the other printer manufacturers? Maybe, like me, you really work for anoher competitor?!?! I do, now! I know about all the technical stuff as I have done Field Service and am a BSEE, but I also have used a 5500 PSCF for a decade or more, refilling cartridges more than 25 times. It's a great machine that spits out great quality and the ink tank lasts 2 months and hundreds of pages. In my humble opinion, give them this link, tell them you will pass the comments on to HP, and become their hero. Any other response will just make you look like the bad guy that tows the company line. It may also attract some crazy who will drop a nuke on your new car!!!! Just ramblings from a common tater eeking out a meager living. Enjoy your retirement and don't forget to look around and appreciate the lovely things and people around you and give God the credit.
