The ink in a dropper does not fall out because - The atmospheric pressure outside the dropper is more and the pressure inside dropper is less.
As the ink dropper is pressed, a lower pressure is created and it sucks the ink due to the ink dropper. After entering into the dropper, the ink will be present at the lower pressure than the outside atmospheric pressure. Liquids like ink cannot flow from lower pressure to the higher pressure. Thus, the ink remains inside the ink dropper without dropping unless more pressure is applied to it by pressing its rubber.

well the ink does not fall out of the dropper because of "pressure difference" inside and outside.
On the sucking of the ink by the dropper there is development of the inside the lesser pressure occur in the dropper , this pressure is less than the outsides atmospheric pressure and we know that the liquids just like ink can't go from lower pressure towards the higher pressure so it does not fall out of dropper.
