Abstract
Certain examples described herein relate to printing systems and methods of operating the same. In an example of a printing system, a nozzle diagnostic mechanism obtains information relating to a condition of a first nozzle set of a print head following a first period of an established printing operation, and a nozzle compensator receives information relating to the condition of the first nozzle set from the nozzle diagnostic mechanism. Based on the received information, the nozzle compensator then causes a second nozzle set of the print head to be operated in place of the first nozzle set of the print head during a second period of the established printing operation. In an example of a method of operating a printing system, status information that relates to a condition of a first nozzle set of a print head is determined during a print production operation. A second nozzle set of the print head is then caused, based on the status information determined, to be operated in place of the first nozzle set to continue the print production operation.
