Mine is 1.2.0A, and it does have a Page Setup option under the File menu, making it possible to use with Leopard... so I guess this is one of those cases where newer is NOT better!
Unfortunately, PrintCD is one of those things that I don't think Epson makes available for download on their website. Still, you might try badgering their support contact for either a newer version, a link to the older version, or an explicit description of what you need to do to get yours to work. (I've been having not much luck with them, though -- so far all I'm getting are generic responses that sound as if the support person didn't actually read my original question.)
