You could try putting scotch tape over both the ink opening and over the vent hole on the top of the cartridge. However, I doubt that these cartridges will be any good after 2 years of storage. I would recommend your daughter sets aside a few dollars a month until she's ready to pick up the printer, then she can just by new cartridges.
