Why does upgrading to Mandrake 9.1 break CUPS?
Mandrake 9.1 uses Foomatic 3.0, there cupsomatic is replaced by foomatic-rip. Please remove all your print queues with printerdrake, then close and restart printerdrake and new queues for the local printers will be generated automatically. You can edit them (for example renaming) by double-clicking on the queue entries. Add queues for your network printers with the Add printer button.
