duplex printing

[stelmo at savba.sk]

Hi!

My problem is that I am not able to print duplex.

I am running debian sarge (cups version 1.1.20)
and the printer is Xerox phaser 6250dp.
(the ppd was downloaded from the xerox homepage)

Let me point out that with debian woody (cups 1.1.14) everything works
well.

Any ideas?

Thanks


 Peter
