PS CS5 color space to jpg color change

After editing a raw file in camera raw then pulling it into CS5 and making the necessary changes I save as a jpg file. The problem is that there is a difference in the color in PS vs the jpg file. I have used Vueprint and the Windows picture viewer to view the jpg. The jpg file color is much more saturated than the image in PS. What am I doing wrong? I will send a few prints to see how they look tomorrow. Your advice will be appreciated.

Thanks in advance
