Here we are:

acrobat = WIN32OLE.new(‘AcroExch.App’)  
doc = WIN32OLE.new(‘AcroExch.AVDoc’)  
acrobat.show  
doc.open(“c:\Program Files\Microsoft Space-Bearing  
Paths\Are\Evil.pdf”, “ok”)  
#doc.printpagesex(0, 0, false, true, true, false, true, true, true)  
acrobat.exit

ruby program:

Does anyone know how to retreive and change the default printer maybe?
