I've tried this system too using Centos 5 but not using Postscript printers.
The nice thing about Windows as a print server is that when you connect for the first time the driver is downloaded to your PC automatically.
That's where I came unstuck because I had to install the driver manually when I connected. That's OK but I use a log on/off script that installs the local room's printers at log on and removes them at log off.
So the real question is: how do we get the U**x box to provide the Windows drivers automatically?
