I'm have an odd issue with certain printers.

When I go to the iprint webpage, the one that is auto generated I notice
some of my printers are missing printer location descriptions. When I go
into iManager to update them I notice they already have Locations. If I try
to change it or even when I don't change anything and hit ok I get this

Exception saving printer information

Service Error: Unsupported operation
Service Other Error: FFFFFCD9
Service Other Error2: 0
Object Identification: asr9k

If I go into a printer which has a print location description and change
something it says success.

I have just updated this server to SP2. Any thoughts or should I try to
delete and recreate these printers?
