I am trying to load a URL in IE and print it to a postscript printer using Win32::OLE. I cannot figure out how to print though. Any suggestions? The code below outputs the following: 
URL: http://www.google.com/
Page Setup
URL: http://www.google.com/
Printing
Win32::OLE(0.1709) error 0x80070057: "The parameter is incorrect"
