Just had to throw out over 0 of HP ink cartridges due to expiration dates. No other reason, as far as I can tell the ink was still good but the printers wouldn't work with those cartridges. The worst part is that this won't be the last time-unless I get rid of those damned HP printers. (And from what I've heard that won't help-most printer manufacturers have taken this route to rip us off.) I mostly use the ink jets when I need to print in color-and I don't print in color a lot. I've learned 2 things over the years. First, when you run out of ink you'll do so when you're on a deadline. Second, if you're limited to a few local stores (like I am-I simply *can't* fly out at a moment's notice to buy an ink cartridge) then you can't count on them having the cartridges you need in stock-and that assumes that they're open when you run out (usually in the middle of the night). So I've learned to keep a spare cartridge 'on the shelf'-but those are the ones that I just threw out! Like I said, I don't print in color a lot and these last cartridges lasted longer than I expected-long enough for my spare cartridges to expire. Thank god I have several ink jets-enough that I could finish the job. But if I can't keep a spare cartidge on the shelf then what the hell can I do? Other than get rid of HP, that is. Suggestions?
