Xerox printer banners on Solaris

Can anyone give the magic incantation to switch off the print banner page generated by the Xerox printing software on Solaris 2.6

xpadmin (ver 3.01.23) shows “banner page disabled”

lpstat -lp shows “banner not required” for both the print and transport devices

lp -oNoBanner makes no difference

I’d like to save some trees …
