Do the HP inkjet cartridges w/ expired dates still work well? If so, how old can they be? -

I need some replacement cartridges for my HP 1200 inkjet printer. There are some sold on EBay much cheaper than stores, but some have expired dates. I am wondering if anyone has had any experience with using expired ink cartridges, and if so, how old can you buy them and still expect them to work as well as the new ones? Thank you.

As long as they are sealed in undamaged foil wrappers and stored in decent conditions, yes, the cartridges should work fine. If, however, the wrapper has been damaged, there is a slight chance that the heads/ink could have dried out.
