Abstract: 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.

Abstract: 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.

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.

Abstract: An apparatus and method for use in printing an image in a multipass printing device, the method comprising obtaining information identifying two or more defective nozzles in a nozzle array, determining that a line of a printed image is associated with more than a first predetermined number of defective nozzles based on the obtained information identifying two or more defective nozzles and selected step sizes, and identifying adjusted step sizes such that no more than the first predetermined number of defective nozzles is associated with any line of the printed image.
