What determines what pattern of dots is best for displaying a particular image? I can't seem to discern a clear pattern for this image.

This is called dithering or half-toning. You can find a lot of papers that have been published on various methods for doing this. Issues include being fast/cheap to compute, being easy to compute locally (as opposed to needing to solve for the entire image at once), and not creating a repeating pattern or moiré. I think that ink efficiency may also be an issue.
