I adding HP LJ4200 printer drivers to my RMS. I downloaded the
from HP. I installed the Win9x and WinNT drivers fine. Whenever I
try to
install the Win2K drivers I get a Microsoft internet Explorer
Error "iPrint NIPPDZIP -12 Unknown error".

I get the same error trying to install the PCL5e, PCL6 and PS drivers

using either iManager or NWAdmin32.

Are there any ideas what this could be?
