You don't mention what file format you are trying to print, or from which applications you are printing.
So I have some suggestions.
1. Set up a virtual printer on the Fiery and select the desired ColorWise settings and choose to print from each system to the same virtual printer, without changing any of your default virtual printer settings.
2. Install Command WorkStation on each of your systems and import the file into the CWS to the print queue. This will again mean that all imports are picking up the same settings.
3. Check the settings of the application you are printing from. For example, if you are printing from PhotoShop identify what the default working spaces are for the job - are these the same accross the applications. Identify whether you are embedding profiles into the job when you print it - are these the same accross the applications?
If you continue to have issues perhaps you can identify the application from which you are printing, is this the same version accross the different platforms? What is the color space of the document? Are you embedding profiles?
You can use the Post Flight report to see how the file is made up, ie. which elements are CMYK, RGB etc.
You can also use the control bar feature to identify if indeed you have the same settings for many of the color features, such as the source profile, destination profile etc.
