Further info, if I take out +autosavesInPlace (was overridden to return YES), it works fine.
This suggests there's more to supporting this new-fangled document model to allow printing to work. Any documentation spells this out?
Working in Xcode 4, the documentation viewer is so incredibly poor compared to Xcode 3 I can't find anything, or rather I can't wait the ten minutes per page it takes to download anything (aside: is there a way to d/l all the documentation and view it locally? We don't all have gigabit fibre to the node).
