I do some computer consulting on the side, and a lot of my clients have the HP all in one Photosmart C7280 printer.
One of my clients had one of these printers stop working and they bought a replacement. I asked if I could have the old one, since they were just going to send it back to HP to recycle.
Well, after 3 hours of working on it, I fixed it.
It didn't come with ink, and I am too cheap to buy Factory Ink, so I bought a set of refillable cartridges on Ebay, along with some ink to refill them once they became empty (the cartridges came full).
When the cartridges arrived, I put them into the printer, and they worked great, for about a week. Then the printer stopped working.
Long story short, I bought a replacement C7280, put the aftermarket cartridges in it, and they have been working great for about a month now.
I have been refilling my own cartridges for years and it looks like I'll be able to do the same for the C7280.
Cartridges cost only a buck or two to refill, and can be refilled forever.
Great way to save a ton of money, especially if you print your own fliers like I do!
