You'll find that laser printers work better than inkjets for harsh conditions like this. I find that the usual owners will never pop for some environmentally controlled storage (temp, humidity) so that's a dead end and inkjet cartridges cost less than such an unit.
Moving to laser fixed the complaints here.

I learned the expensive way not to leave my ink cartridges in my printer when the printer will not be used for many months. So the last time, I took the cartridges out and put them back into the foil and boxes that they came in and placed them in the desk drawer. This is a very arid country so the humidity might be as low as 10% and the temperature as high as 85 degrees. After installing the cartridges and trying to print there was nothing on the page, so I did what someone had once suggested and that was to run the cartridges under hot water. That worked, at least for one copy. Haven't tried any more yet. Would I be better of putting them in the refrigerator which is set on the warmest setting while I am gone?
