ppm connects over the internet in the default mode.

I you do not have interned connectivity, then you have to go find the .ppd file, download it yourself. Then you can use ppm to install it. look at: ppm 10xx. If that doesn't work search for PDL .ppd or other variations on this theme. Get the .ppd file onto your machine locally via "sneaker net" or whatever and then use ppm.
