It is a hardware asjustment down in the printer body.  The setmargins
operator at least on versions 47.0a and below, shifts the image
electronicly such that it can be moved over into the imageable area.
The PS-Executive software from QMS in Mobile Alabama does it.  The
basic approach is to print out an set of crossed lines exactly 1 inch
from the bottom and left edges.  Then measure the diffrence and use
setmargins to adjust the image.  The command is there in order to 
compensate for mechanical tolerance error in the construction of the
machine.
