Why I do not attempt to store inkjet cartridges
The cartridge supplied with the HP Deskjet 932C doesn't hold much ink, so when I purchased the printer 3 months ago, I bought a 2-pack of 45A -- I hate to run out of ink. I just ran out of ink in the small cartridge, and sadly found that both 45A cartridges had completely dried out. I sure wasted a lot of color ink trying to decide what was wrong! I went back to Office Depot where I purchased the printer, and was advised that I don't use enough ink to warrant buying a 2-pack because they are almost sure to dry up before I would need them. So I bought a single... and voila, the printer is back to its normal wonderful self... Yes, the cartridges that dried out were still under warranty with both the store and HewlettPackard, so I have been reimbursed.
Hewlett Packard 45A Black Ink Cartridge
A great work horse! I've used 20-25 of these cartridges over the past few years, with consistently excellent results. The print is always clear, I seem to get over 500 text pages per cartrige, and unlike some earlier generation models it doesn't clog when the ink level runs low.
Refill Kit from Dataproducts works
I agree with some of the reviews that the cartridges don't last very long and are expensive. I tried a refill product from Dataproducts for both b&w (51629A)and color cartridges (51649A). Both work well. I didn't trust the cover for the color refill and used the old one by attaching it with tape. Works fine so far. Hope this helps.
