Assuming you are talking about the version from psutils, then I believe this just orders or select pages for printing. To the best of me knowlege it is not capable of setting your printer into duplex mode. Duplex mode is usually controlled by some printer/manufacturer specific job control wrapper around the postscript such as HP's JPL. There may also be postscript commands which will switch to duplex but these are also likely to be somewhat printer specific. Briefly a generic solution for postscript printers is unlikely. But there are print systems that understand about specific printers and insert the job control wrapper. I believe the simplest way to achieve what you want is probably to install the Cups print system. Then something like: % lp -o sides=two-sided-long-edge filename should work. > > Would someone have a ready example: > > pstops 'MagickSpell' input.ps duplex.ps How is this mystical command line constructed? Is duplex.ps some library file you obtained from somewhere? If it contains PS commands to switch to duplex it would probably need to appear ahead of your input. Malcolm
