In one example, a system to fill or drain a reservoir in a printer includes a controller to set a unit to a total capacity of a container divided by an integer greater than 1, a container sensor to sense the container connected to the printer, and a pump to pump, in set unit increments, at least one unit of a printing agent from the container to the reservoir or from the reservoir to the container. In one example, a memory having processor executable instructions to generate a graphical user interface displaying, during the transfer of a printing agent from a container to a reservoir in a printer or from the reservoir to the container, an animation showing a changing volume of the printing agent in the reservoir and a corresponding changing volume of the printing agent in the container.
