1. A fluid extraction system in a printing device comprising:
an interface configured to fluidically and electrically couple an external removable fluid extraction reservoir to the printing device, wherein the external removable fluid extraction reservoir has a memory to store data;
an internal fluid reservoir;
a controller configured to receive the data from the memory and based on the data received from memory of the external removable fluid extraction reservoir, initiate a fluid extraction operation, wherein fluid from the internal fluid reservoir in the printing device is passed to the external removable fluid extraction reservoir; and
a fluid level sensor disposed in the internal fluid reservoir to define when to terminate the fluid extraction operation.
