I'm trying to change the printer description and location in iManager via iPrint>Manage Printers and going to the Information screen. This works OK, except for the HP Laserjet 2100TN printers, strangely enough, where I get the following error message as soon as I click "Apply":

Exception saving printer information

Service Error: Unsupported operation
Service Other Error: FFFFFCD9
Service Other Error2: 0
Object Identification: Undercroft HP LaserJet 2100TN

Can't find anything in the TIDs - any ideas out there? Help will be much appreciated, thanks.
