Bear with me: I am not at all sure this is the correct answer; I have not your printer and have only limited access to the settings.
Looking at the installation files, it appears that the printer hardware likes a minimum print margin of 0.167 inches. If that is indeed the case, then the smallest achievable margin might be defined (to the nearest hundreth) at 0.17 inches.
Given that restriction,
Set your Word document > File > Print > Margins > Custom Margin >
tab Margins (to no less than) .17 >
OK
Note that this does not include "booklet" settings, which by definition, might require a larger "gutter" margin to accomodate the booklet style print option.

Note:
IF your printer is an Enterprise edition, then you might be able to take advantage of the Custom Form setup:

Good Luck!
