	I have a LaserWriter IIg and a LaserWriter NTR that I wish to hide
from direct access by Macintoshes by changing the LocalTalkType to
something other than LaserWriter (ie LW Spooler). The following script works,
but the printer reverts after a reset (ie power cycle).

true 0 startjob (%LocalTalk%) <</LocalTalkType (LW Spooler)>> setdevparams

Various permutations of %LocalTalk% like %LocalTalk_NV% will still fail
across resets. Is there an incantation that works?

First of all, there are two passwords on a Level 2 machine: the startjob
password and the system parameters password. You are using the startjob
password by invoking startjob. Try adding the /Password key with a value of
the system parameters password to your setdevparams invokation.

Secondly, there is no guarantee that all settable device parameters will be
stored across power cycles. This depends on how much non-volatile ram is
available. Check your printer supplement for which values are persistent.

Finally, device parameters do not obey save/restore, so there is no need to
set them outside of the server loop. So your code could be:
  (%LocalTalk%) <</Password xxx /LocalTalkType (LW Spooler)>> setdevparams
