Abstract: According to one example, there is provided a system for compensating for changes in printhead-to-printhead spacing in a printing system having multiple printheads mountable on a printhead support. The system comprises a measurement system to determine a change in printhead-to-printhead spacing between different ones of mounted printheads, and a processor to determine compensation to be applied to the printing system to compensate for the determined change in printhead-to-printhead spacing.

Abstract: In one example, a first swath is caused to be printed by a print unit on a media. The media is advanced with respect to the print unit. For a nominal second swath to be printed to beneath and adjacent to the first swath, a plurality of adjustment regions along the width of the nominal second swath are determined in accordance with a profile of non-constant advance errors for the media. An adjusted second swath is formed by, for each of the regions, adjusting the height of the nominal second swath in memory based on the determined amount of advancement error for the region. The print unit is caused to print the adjusted second swath on the media.

Abstract: An image forming system includes a print unit to print a plurality of swaths to form an image on a media, a media transport unit to transport the media to the print unit and an advancement error determination unit to determine an amount of advancement error corresponding to the transportation of the media. The image forming system also includes a swath adjustment module to dynamically adjust a swath size of a respective swath.
