Newbie question: which one is the right/left print core

[Ndimensional]

Hi, well, may be a stupid question, but I have looked into the guides etc. and not found a hint. It may be, that I have overseen it.
I am using an Ultimaker S3 which has dual extrusion. Now Simplify3D differentiates between "right" and "left" extruder. But what is "right" and "left" ? Right and left when I stand in front of the printer ? Or when the printer "looks" to me ?
So:
me
left right
printer

or
me
right left
printer

Well maybe a stupid question, but if so, it for sure could easily be answered....

I believe left and right is defined when you are looking at the printer. It is from your vantage point.
