1. A system operable to determine a condition relative to an image being printed on a medium, the system comprising:
a printer carriage operable to move in a first direction, at a first speed or a first acceleration, to print the image as a plurality of sections,
wherein each section is printed one after another on the medium in a second direction different from the first direction;
an imager located downstream of the printer carriage and operable to move in the first direction to capture a sample image of each printed section of the image of the plurality of sections of the image printed on the medium,
wherein the imager is operable to move in the first direction and move independent of the printer carriage at any one of a second speed distinct from the first speed or a second acceleration distinct from the first acceleration, and
wherein the sample image of a printed section of the plurality of printed sections of the image is captured by the imager after the printer carriage completes printing the section of the image on the medium, and after the medium advances; and
an inspection mechanism operable to stitch each sample image of each printed section of the image of the plurality of printed sections of the image into a stitched image and determine a condition relative to the image based on the stitched image.
