I'm glad to see that something is being done.
For those that may have missed it being discussed here in
rec.photo.digital I kept the following for future reference of how to
reset expiration dates.
My HP932c [purchased Nov.00] is not affected but my next printer would
be.
Google is your friend:
http://www.google.ca/search?hl=en&q=HP+resetter&meta=
.... try search strings like "Epson resetter" & "smart chip ink
cartridges" <no quotes> to find more.

why? the manufacturer would probably tell you that the dates are to
ensure a good experiance with their product through the use of fresh
cartridges. i would tell you that the dates are so that they can sell
you more cartridges. i think all the majors have implemented some sort
of scheme like this... the cartridges have a chip built into them that
can be reset if it is considered 'expired' or if you wanted to remove
and refill it. search the web for "hp resetter" (or for epson, "epson
reset tool") and you will find several... a manual way of reseting the
cartridge/printer to accept the expired or previously used cartridge
is listed at the link below. there are three methods and only one may
work on your particular model, but try them all with particular
attention to the third method suggested which is the easiest,
cheapest, and simplest, but may not apply to your model printer.
it may be more economical to purchase a non-hp cartridge than the
resetter tool and ink refills for a person that does not print very
often.
