Inkjet cartridges are expensive. They also do not have a long shelf life once installed. If you use the ink jet printer frequently, of course, the cartridges run out of ink, but what's worse is that when you don't use them and they dry out then become useless or at least, print with very bad quality.
To get the most out of your ink jet cartridges, you can store them in an air tight container or zip lock bags any time you are not using them. Even if the printer will sit for a few days, you should remove the cartridges and seal them up. Air is the enemy of ink cartridges, so this will help prolong their usable life.
