Abstract: A printing system comprises a processor to obtain image data comprising first image data defining a first color plane of the image and comprising second image data defining a second color plane of the image. The processor is to manipulate the image data such that the second color plane is shifted relative to the first color plane in a media axis direction of a printer. The printing system comprises a printer to print the manipulated image data with the printer.

Abstract: In one example, a method for wiping the face of a printhead includes wiping across the face of the printhead and then wiping along the face of the printhead with a web of cleaning material. In another example, a wiper for wiping a face of a printhead includes a rotatable shaft having an axis of rotation and a helical blade affixed to the shaft. The helical blade is simultaneously rotatable on the shaft against the face of the printhead and translatable along the face of the printhead in a direction parallel to the axis of rotation.
