Claim 12:
13. A system of inkjet printers comprising:
a plurality of inkjet printers and a system controller operatively connected to each inkjet printer in the plurality of inkjet printers, each inkjet printer in the plurality of inkjet printers comprising:
at least one printhead;
a media transport configured to move media sheets past the at least one printhead;
an image sensor configured to generate image data of one of the media sheets after the one media sheet has passed the at least one printhead; and
a controller operatively connected to the image sensor, the at least one printhead, and the media transport, the controller is configured to:
receive image content data for a print job;
identify a first number of inkjet operations for each inkjet in the at least one printhead to print media sheets using the image content data for the print job in a first orientation;
identify a second number of inkjet operations for each inkjet in the at least one printhead to print media sheets using the image content data for the print job in a second orientation;
identify a first magnitude of cross-process direction displacement error using the first number of inkjet operations and a cross-process direction displacement error previously measured for each inkjet;
identify a second magnitude of cross-process direction displacement error using the second number of inkjet operations and the cross-process direction displacement error previously measured for each inkjet; and
transmit an identification of the orientation of the image content data associated with the smallest magnitude and the magnitude of the cross-process direction displacement error corresponding to the identified orientation; and

the system controller is operatively connected to each of the inkjet printers in the plurality of inkjet printers, the system controller being configured to:
receive a print job;
send the print job to each inkjet printer;
receive from each inkjet printer the identification of the orientation of the image content data associated with the smallest magnitude and the magnitude of the cross-process direction displacement error corresponding to the identified orientation;
compare the magnitudes of the cross-process direction displacement error received from each of the inkjet printers to identify the inkjet printer that send the smallest magnitude of the cross-process direction displacement error; and
send to the inkjet printer that sent the smallest magnitude of the cross-process direction displacement error an instruction to print the print job.
