[Pkg-cups-devel] Bug#168954: cupsys: Duplex not working -- a psutils bug? [patch]

[Ronald Lembcke]

Hi!

I've had the same problem with duplex not working when printing
Postscript generated/modified by psutils. I'm not sure if it's a bug in
psutils or cupsys. If you think it's a bug in psutils please forward
my message or reassign this bug.

The bug can be fixed either in Cups or in psutils. Psutils disables the
command /setpagedevice. But cups inserts the commands to disable
duplex-printing _after_ the command has been disabled.  Obviously either
duplex-printing and other options have to be enabled earlier or the
command must be disabled later.

You can try the following patch (to psutils) which does the latter. It
works for me and I didn't notice any ill side effects.
