Abstract: According to an example, a printing system may include a drop ejecting element and a fluid circulating element corresponding to the drop ejecting element. The printing system may also include a logic device that is to receive a data stream addressed to the drop ejecting element, determine whether the data stream indicates that the drop ejecting element is to be energized, and in response to a determination that the data stream does not indicate that the drop ejecting element is to be energized, energize the fluid circulating element.

Abstract: In some examples, a fluidic die includes fluidic actuators, switches, and electrically conductive lines in an electrically conductive layer of the fluidic die. The electrically conductive lines electrically connect the switches to respective actuators. A first dimension of a first electrically conductive line is different from a second dimension of a second electrically conductive line to match a first resistance of the first electrically conductive line having a first length to a second resistance of the second electrically conductive line having a second length different from the first length.
