This is the error I get when attempting to associate an iPrint printer
with a printer queue in iManager (Migrate QMS to iPrint):

Migrate QMS to iPrint Failure
A newer schema is needed for this functionality

We have NW6.5 SP3 plus iPrint updates. (We are testing SP4a now.)
iPrint has worked flawlessly otherwise. I wasn't able to find anything
by googling, or in the Novell KB.
