Dynamic power thresholds for printer device pens

摘要

An example device in accordance with an aspect of the present disclosure includes a controller to generate predicted and past power consumption values for at least one pen of a printer device, for a sliding window of future and past time, as a function of ink delivered data scaled by print speed data. The controller is to assign a dynamic power threshold for the present time as a maximum power consumption value of the sliding window, and stop power delivery to the at least one pen if the present power consumption of the at least one pen exceeds the dynamic power threshold by a margin.

1. A device comprising:
a controller to generate predicted and past power consumption values, for at least one pen of a printer device, for a sliding window of future and past time, as a function of ink delivered data scaled by print speed data, wherein the controller is to position synchronize the dynamic power threshold to the at least one pen, based on offsetting the ink delivered data and print speed data corresponding to a position offset of the at least one pen relative to the printer device; wherein the controller is to assign a dynamic power threshold for the present time as a maximum power consumption value of the sliding window, identify whether present power consumption of the at least one pen exceeds the dynamic power threshold by a margin, and if so, stop power delivery to the at least one pen.
