I'm pretty sure you don't need to specify MODULE_01 if you're using LTSP 
4.2 (included in K12LTSP 5.0EL).  I don't think it hurts anything, but 
you might want to take it out and see what happens.  Everything else 
looks good.

I'm using local printers in K12LTSP 5.0EL and my configuration is the 
same as yours except that I use etherboot instead of PXE, and I assigned 
my printer using the hostname (which I have a DNS record for) instead of 
IP address.  But the way you're doing it looks like it should work.
