Nice idea, but...
1. I would *really* hate to wait to get the new properties into
Printer. I think we ought to leap on those with both feet. Deprecation
is slightly less important.
2. The time between public CIM versions is three months, not four to
six. If we miss version N, then version N+1 is published three months
later. We think that it is longer because of the delta between
CR-approved and next schema version published dates.
Let me ask Crandall if we can possibly fudge the deprecation for the
properties that we want to move from Printer to PrintService. If we are
going to keep the same property name and semantics, maybe it is not
crazy to say "This property will be moved...."

Hi Bill,
Basically that's what I'm saying.
But actually PrintService wouldn't be delayed at all. It just wasn't
going to get updated in the next cycle with the wrapup of Printer and
subunits.
The main update of PrintService is too large to do now.
Until we finish Printer and the subunits, we don't have a "package" of
Print Device classes to recommend people implement. And remember we
need two independent implementations to go from CIM Experimental (no
stability guarantees) to CIM Final.
Cheers,
- Ira
