Thinapp Package Not Printing in Windows 7

I was able to ThinApp one of our Custom Software on Wndows XP and the application works fine on clients with Windows XP, but in Windows it will not print. It does not even see any of the Printers that are installed.

I have installed the application on Windows 7 and the printing works fine.

I have created a ThinApp on a Windows 7 but it does not print either.

Can anyone help with this issue?

Thanks
