You can print out a series of strips with all the settings. I've done that  
but haven't kept it and i don't remember in which order they came, but it  
was easy to see. Print on the same piece of PCB entering a different  
offset each time.

Also there is a calibration procedure that will print bars with the  
different "variable droplet size" sizes. Although that may not translate  
to any printer settings.
