Ok. I understand the need for the {0,4} now! Unfortunately in the 6510 ppd definition in the drv file the .Duplex defintion is 102 lines further down the file.
I will test with a value to compensate for that. But I still think that this is just sticking a bandage on a bandage. I found a note somewhere on the apple site about setting PageSize and MediaSize constriants which looked interesting (you need to set both). I wonder if we could set up constraints such that selecting a *Duplex option needed a .Duplex paper size. At quick glance though this looks difficult if not impossible.
