The shelf life of some cartridges (Epson) is about two years from date of
manufacture. I'm not sure what it is for HP. However, this is only true for
unopened factory sealed packages.

A search on the net produced some relatively low prices on the cartridges
for your Daughters printer. The prices I found were less than twenty
dollars.

I would give some thought to Donating the printer to a school or a needy
family. Two years from now printer cartridges may not be available.

"Vacuum pack them, shrink wrap them, or hermetically seal them, two years
from now they will probably not work due to the fact the ink will still dry
out or at best congeal. For the sake of argument, I surely wouldn't want to
put them in a printer and chance they will render it useless.

A search on the net produced no results... Sorry. If anyone can come up with
an exact method, I would like to hear about it.
Sincerely,
