iPrint IPP gateway

I'm trying to test iPrint in ouy test environment
but when I try to create a printer with imanager
I can't seem to select "NovellIPP gateway" (only "Novell LPR gateway")

IPPSRVR.NLM is loaded

I can create ndps printers without any problem.

I'm using NW6(+SP2) & ZfD4

I also red in the NDPS newsgroup that the IPP gateway is no longer
available once SP2 is installed?
