How? Here's the manpage for lpadmin:

  lpadmin [ -E ] [ -h server ] -p printer option(s)

I tried using the following variations:
    -h server1 -h server2   # it only picks the second server listed
    -h server1, server2     # doesn't work
    -h serever1 server2     # doesn't work

What's the correct way to specify multiple servers for lpadmin?

Thanks!
