How do I set up my printer for wireless?

I have a Kodak ESP 5 that is NOT stand-alone wireless enabled. It is connected to my MacBook running OSX 10.6.8 and AirPrintActivator 2.0b6 so I can wirelessly share my printer with my iPod and other Macs. I have a PC though that runs Win Vista Home. It there any program that I can get so I can share my ESP 5 with my PC through my Mac? OR vise versa?
