A print format adjustment system includes a receiving module, a visual condition determination module, a print format determination module, and a print control module. The receiving module receives content for printing in a first print format. The visual condition determination module establishes the sharpness of vision of a viewer in front of a display, at a predetermined view distance. The print format determination module determines a second print format based on both the first print format and the visual condition of the viewer. The print control module prints the content in the second print format.
