	Unfortunately, I have no idea how Apple keeps track of the different
	versions of LaserPrep in the printer. From what I can tell of the
	LaserPrep itself, there is no version information included in the
	LaserPrep procset.

	When you figure it out, you should post to the network -> a
	lot of people ask this question!  What Apple does with
	LaserPrep is not really known to us,
	we have no formal agreement to exchange information on LaserPrep
	related	problems.

Well, this is a kind of silly but I just found out the way to do this
right after I posted my message. Anyway, I foun dout the answer in
Apple laserwriter driver. Here is the code that will reset the printer
if the prep file loaded is not version 70

%!PSAdobe
/md where{/md get /av get cvi 70 eq{(1)}{ systemdict /quit get exec
}ifelse}{(0)}ifelse = flush
%%reset if prep is not version 7.0

I hope others can use it.
