I can successfully create an NDPS object with iManager. But when I go
back to modify that printer to add drivers, etc. I receive this error:

"Attribute could not be found: Printer Agent Name"

At this point I crack open the printer object in C1 and add the Printer
Agent Name and PSM Name attributes in the Other tab. This fixes the
error in iManager.
Does anyone have an idea as to why these attributes aren't be added when
a printer is created?
