摘要： In some examples, a printing system comprises a controller to determine, during a print operation, first status information that relates to a condition of a first nozzle set of the print head, and second status information that relates to a condition of a second nozzle set of the print head. In response to determining from the first status information that a number of malfunctioning nozzles in the first nozzle set does not exceed a first threshold value and determining from the second status information that a number of redundant nozzles in the second nozzle set exceeds a second threshold value, the controller is to cause the second nozzle set including the redundant nozzles of the print head to be operated in place of the first nozzle set to continue the print operation. In response to determining from the first status information that that the number of malfunctioning nozzles in the first nozzle set exceeds the first threshold value, the controller is to interrupt the print operation and instructing a maintenance operation on the print head.

摘要： According to one example of the present invention there is provided a method of printing, with a printer, an image on a substrate, the printer comprising a substrate support. The method comprises obtaining an image to be printed, determining an offset position of a substrate positioned on the substrate support relative to a predetermined reference printing position, and controlling the printer to print the image to be printed at the determined offset position.

摘要： 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.
