The Postscript Cartridge for the LJII is different than the
cartridge for the LJIII.  The only explanation seems to be that
HP wanted to get a small headstart on the other cartridge makers
for the LJIII(read: Greed).  

The LJII looks for a key word on the cartridge to determine if 
it is a program (eg Postscript) or data (eg font).  HP changed the 
key word for LJIII.

So you have to buy two cartridges if you want to run Postscript on
both machines.  Adobe and Pacific Page have cartridges for the
LJII.  Adobe's is offical Adobe, while Pacific Data Products' is 
licensed from Phoenix (clone).  HP's cartridge is Adobe Postscript
and runs only on the LJIII.
