Yes, it does not get printed. Moreover, after one job printed in duplex
printer gets stuck in duplex mode, ignoring DUPLEX environment...

I also think so.  Would be very grateful if somebody explains me how to
set it up properly...

It looks like setting DUPLEX environment is not enough to switch the
printer to duplex mode. I myself have the only idea: to send escape
sequence which sets simplex/duplex mode before each task and send "eject
page" sequence after each job. How to send escape sequences to the PS
printer?

Thanks,
