You should always test output using good color reference images designed for that task. The color reference images RGB values are such that they are set for output and are editing and display agnostic. Test the output this way and examine for the same color issues so we know it's not your image-specific issues causing the problems:

Is your workflow color managed at any point? Is your display profiled? Is your printer profiled? If not, that is a good first step.  If so, please post more detail about your problem.  Which tools are used, media, profiles etc.
