Zusammenfassung:	An example printing device includes a plurality of printing agent reservoirs and a printing assembly that is to emit printing agent onto print media. In addition, the printing device includes a pumping assembly fluidly coupled between the plurality of printing agent reservoirs and the printing assembly. The pumping assembly includes a motor and is to transport the printing agent from the plurality of printing agent reservoirs to the printing assembly. Further, the printing device includes a controller coupled to the motor. The controller is to: receive a work parameter of the motor; receive printing agent usage data; and determine that a first printing agent reservoir of the plurality of printing agent reservoirs is empty based on the work parameter and the printing agent usage data.
