Right-click on My Computer and select Manage.

Click Device Manager in the left pane.

Find your Printer in the list, right-click and select Uninstall.

Reboot your computer. Make sure the printer is on before it finishes starting up, and then allow it to queue the driver setup. When the prompt appears...insert the driver CD and continue through the wizard to completion.

Let me know if that works.. (we'll work on sound issue later).
