Title: Monopoly in Action
Review: Only buy an HP printer if you're willing to pay their high ink prices. I bought the 6310 after my previous HP printer bit the dust (after only 3 years). The 6310 happened to use the same color cartridge as my old printer (one reason I bought the 6310). But when I put the cartridge in my new printer, I kept seeing thin blue lines on my printouts and aligning the cartridges didn't help.So I contacted HP support. Without going into all the details, I determined that HP is "locking" out remanufactured cartridges by having their HP software print blue lines. When I run a test page from the printer (i.e. not through the computer), there are no blue lines and my cartridge worked fine in the old printer . . . so it's NOT the cartridge no matter what HP says. It's a monopoly in action!!!
