i use open enterprise server (linux)
i have problem in installing the first printer from imanager
it gives me the error:

Print Manager printmanager.value is not loaded.
It must be loaded to create a new Printer Agent.
Select the Manage Print Manager task to load.

i checked that the print manager is running

another problem when i try to add new drivers from "Manage driver store"
it gives me:
IPP Error: 0xF0193
HTTP Error: 403

should the cups be started to solve these problems?
