Can anyone point me as to the means of loading OS X PPD drivers onto an
iPrint Server.

NWADMIN - is out of support andonly covers Windows
CONSOLE ONE - does not seam to support iPrint

iManager - from a Mac does not support loading from system
iManager - from a PC seems to be looking for files with .PPD extensions
but Manufacturer we site seem to have .hqx files containing .pkg

What am I missing ?
