Samsung 2150 Problem

[brsboarder]

I just got the 2510 not 2150, and am having problems. I'm trying to print double sided. The manual says I can, and when I go to print something, I have the option of choosing the binding, long or short side, long like a book, and then a box that says double sided gets checked. However, it doesn't print that way. Does anyone have this or a similar printer and know what to do.

Sorry for the hosting problems, anyways, you can see from the link that the two sided option is chosen

I tried to download the file, but didn't see en.lproj anywhere. Please??

Someone said it has to do with the outdated drivers. Does anyone know if I can use any other drivers for the printer to make it work? A new samsung driver or anything else?
