Server Install v1.7.3 can't connect to Windows 7 client

We have done a Server Installation using Version 1.7.3 and can connect to the Print Server from Windows XP computers, but it doesn't work from Windows 7 clients.

I must admit during the install of version 1.7.3 it did give options for all the OS's that we would need to install the Printer drivers on and Windows 7 was NOT one of the options - is this the reason why?
