Comment 7 for bug 403169

I forgot to say that I'm using Kubuntu Maverick with Kde 4.5.2. I solved it for Okular but I still have problems in Acroread. I guess it is related and I don't know how to fix it. The message is the following:
'lpr: Bad copies value 0.'
On the other hand, do you know if there is a similar workaround to put duplex by default in Okular, because now each time I print something I have to modify the options.
