GPEDIT doesn't show all items

From a post before in this Newsgroup, I start using MS Print migrator Tool
to move printer driver from one server to another. Looks like a very good
tool.
Unfortunately, I receive a error message:
WARNING: Kernel Mode Drivers (version 2) are blocked on the target machine.
Disable Kernel Mode driver blocking and re-run Printer Migrator."

Surfing, I found a solution
(http://www.chicagotech.net/others/pritermigrator1.htm), but wehn I try to
follow the instructions, when I go to "GROUP POLICY EDITOR" > Explorer
Computer Configuration > Select Administrative Templates, I don't see the
"Printer" Item. I go to another server, and Under "ADMINISTRATIVE TEMPLATES"
I can see items like: NEtwork, System and Printer.
How can I do in order to make this items to be visible in the GPEdit.msc.
or, there is another way to disable Kernel Mode using Registry Editor
maybe???

thanks in advance for any help...
