Probably needs one or two PJL commands tacked on to the front of the prin=
t job
and one or two more at the end to cancel the duplex. Have a look for the =
PJL
commands supported by your printer -- try an HP web site -- and write a p=
rint=20
filter that can add in the commands either by the selection of a duplex q=
ueue=20
or by passing options to say LPRng with lpr -Z
