Registry Hive Import - User Not Local Administrator

[SarasotaIT]

I am trying to automate the setup of the printer environment of 150 users that all have local printers attached to their w/s. I have set the advanced settings of the printer and exported the registry hive [HKEY_CURRENT_USER\Printers\DevModePerUser] to a .reg file on the server. At user logon, I wish for all users (who use roaming profiles) to be forced to import this hive into their registry, via a script, to ensure proper printer settings. The logon script is a .bat that contains: regedit /s \\server\Public\registry\decal.reg. It fails because the user is not a local administrator. How does one script this import when the users are not local administrators of their w/s? I have tried using regedt32 and setting the permissions on the printers hive to everyone-allow full control, but even that fails.
Much thanks in advance!
