Hello Johannes,
  Unfortunately, this is a bizhub 1250, a major league sized device that's 
used by various folks across the University, and not my personal or group 
printer.  There's too many other people using it for me to mess with 
resetting the defaults (which hopefully, I didn't do by playing around 
with the "SET DEFAULT" commands!^)

I'm writing my printer output to a file to check what's actually getting 
sent. Here's the top of the file (the ESC is actually there, just not in 
the copy I made):

2345X at PJL
@PJL SET DRIVERJOBID="ACDE48A5E35902221439490479"
@PJL SET STRINGCODESET=UTF8
@PJL SET USERNAME="pmitchel"
@PJL SET USERMEDIANAME="DV02"
@PJL SET USERNAME="DV02 forms"
@PJL SET DUPLEX=OFF 
@PJL SET PILEMODE=ON
@PJL SET JOBNAME="Microsoft Word - PMerged.docx"

I know that it's getting the call for the DV02 form, but I still seem to 
print Duplex mode.

Continuing to wrestle with this! Thanks for allthe help so far.

FTR, here's what od -bc shows me about the top of the file:

0000000 033 045 055 061 062 063 064 065 130 100 120 112 114 015 012 100
         033 % - 1 2 3 4 5 X @ P J L \r \n @
