Just after you install RC2 go to Mandrake Control Center | Hardware | Printers. It installs software and then leaves a blank dialog. It also blows away the Configuration and What to do menus.
To get that printer dialog working, you have to manually run printerdrake and specify a printing system. Then when you load mcc again the dialog can be used. Printing options also appear in the menus. Running update-menus gets the menus in order again. After all this my mouse was stuck with the busy cursor.
