The LaserWriter will reinitialize if it sees someone trying to print with a
different version of LaserWriter and Laser Prep, regardless of the size of
the difference in version numbers.
The drivers are not truly "associated" with a particular system release,
they just happen to be distributed with that release. You can use 6.0.1
LaserWriter and LaserWriter Prep with System 6.0.2 if you like, just as you
can use version 5.2 LaserWriter and LaserWriter Prep with System 6.0.5.
Use the suggested print driver that is best for the software, and
standardize the whole network on that version to avoid loss of time due to
reinitialization of the printers.
