Thanks, but driver? I'm sending a Postscript file to a remote Postscript 
printer. This is the printcap entry:

	nyp2:\
		:rm=nyp2:\
		:sd=/var/spool/lpd/nyp2:\
		:lf=/var/spool/lpd/nyp2/log:\
		:af=/var/spool/lpd/nyp2/acct:\
		:sh:

My question was, how to can I manipulate an existing Postscript file, to make 
sure, it is printed in duplex mode... `pstops' is supposed to be able to do 
it...
