A few thoughts.....
Make sure that you have downloaded and installed Bonjour Print Services for Windows v2.0.2 on the PC.
If you have previously installed Bonjour, delete the current application and download and install it again.
Run the application to see if it will find your printer.
Not all printers are supported, so if Bonjour does not find your printer, you will not be able to reach the printer unless you install it at another location.
