From the Apple LaserWriter Reference:

You can write new values to the EEROM, which can store the
persistent parameters only a limited number of times before
wearing out.  Each location of the EEROM is capable of
approximately 10,000 writes.  For this reason, you should use
the EEROM only for parameters you expect to change infrequently.
The copy count is an exception -- it is implemented in such a
way that the wear is distributed over many locations.

Note: the LaserWriter IINTX uses ZPRAM in place of the EEROM.
ZPRAM can be written to an infinite number of times.  Therefore,
the statements just given regarding storage of the persistent
parameters in the EEROM does not apply to the LaserWriter IINTX.
