1. A print cartridge, comprising:
- a housing;
an ejection device mounted to the housing, the ejection device to dispense a composition;
an array mounted to the housing and comprising a visible marker, the visible marker to store information regarding performance of the ejection device; and
a circuit coupled to the ejection device, the circuit to;
measure performance of the ejection device and create information regarding the measured performance of the ejection device; and
actuate the visible marker to store the information regarding the measured performance of the ejection device in the visible marker, the visual marker having a physical characteristic to be changed in response to the actuation by the circuit, the changed physical characteristic persistently storing, in the visible marker, the information regarding the measured performance and being visually perceptible from outside the housing.

Abstract
Examples of an apparatus and method are disclosed herein. In an example of the method, the performance of an ejection device that dispenses a composition is measured, information representative of the measured performance of the ejection device is generated, and the information representative of the measured performance of the ejection device is recorded so that the information is visually perceptible.

19. A method, comprising:
-
measuring, by a circuit mounted to a housing of a print cartridge, performance of an ejection device that dispenses a composition, the ejection device mounted to the housing of the print cartridge; generating, by the circuit, information representative of the measured performance of the ejection device; and recording, using a visual marker mounted to the housing of the print cartridge, the information representative of the measured performance of the ejection device so that the information is visually perceptible, the visual marker having a physical characteristic to be changed in response to the recording responsive to actuation by the circuit, the changed physical characteristic persistently storing, in the visual marker, the information representative of the measured performance and being visually perceptible from outside the housing. - View Dependent Claims (20)
