Subject: Re: Using Ruby to change printer preferences in Win32

This works for me:

require 'win32ole'
wn = WIN32OLE.new('Wscript.Network')
wn.SetDefaultPrinter('\\\mpe-ls1\mpe01lp')
puts("finished")

I'm not sure how the backslash escaping is working there, but like I
say--that's working for me...

HTH,
