Having been a big user of iPrint to distribute network printers to
windows workstations, I have recently started at looking at using iPrint
to deploy printers to our apple macs, however i cannot fathom out how to
upload mac (*.ppd) drivers to the broker.

For example i downloaded the os x driver for a an hp lasrjet 4350
printer (from hp) which comes down as a *.dmg file when i run the
download it installs the software, however becasuse it's a mac i can't
use the add from system function, similarly i cant open the *.dmg file
on a windows pc.

How then can i extract the ppd drivers and install the drivers to the

I hope someone can help.
