Abstract: A method of configuring an orientation-agnostic inkjet print module for use in either one of first or second module orientations relative to a media path, the second module orientation being rotated 180 degrees relative to the first module orientation. The method includes the steps of: configuring a key assembly to correspond with either one of the first or second module orientations, the key assembly determining a printhead orientation of a respective printhead relative to the inkjet print module; and configuring a switch to correspond with either one of the first or second module orientations, the switch being operably connected to controller circuitry distributing data signals to the printhead via first and second data paths. The switch inverts distribution of the data signals between the first and second data paths.
