In the past when working with NW5.1 and NWAdmin and deleting a printer
object, the printer agent was not removed.
The printer then became a "Public Access Printer".

How does this work with NW6.5 and iManager?

You now have the options to:

1. "Delete Print Object" where you can select to delete a printer object.
2. "Manage Print manager" > Printer Agents > Tasks > Delete (Printer Agent)

Whats the difference between these two options?
