Not sure about redirecting stdout on windows, best i can see is that
you redirect to a temp file
and print that.

if the file is a recognised type on windows (e.g. .pdf and adobe
reader is installed)
try this :
require 'win32ole'
SHELL_APP = WIN32OLE.new('Shell.Application')
SHELL_APP.ShellExecute("test.pdf", '', "C:\\Temp", 'print', 0)


otherwise you can try printing to a shared network printer:
PRINTER = "\\\\192.168.1.1\\shared_printer"
system "print /d:#{PRINTER} C:\\Temp\\test.txt"
