I just tripped over myself :-) After reading this excellent discussion of dpi (http://www.danheller.com/tech-dpi.html ), I think the problem might just be dvipng. The "problem" is that while the PNGs look good on the screen, they look horrible in the printer. I tried creating some PNGs with with dpi's of 1000. The images were very pixelated. If you print such a low quality image, it will look horrible, no matter how high the dpi. 

I tried using the Q switch but that didn't seem to do anything. Maybe there is some type of combination of switches that produces better quality PNGs? Or an alternative program that does the same thing?
