On Windows 7 Home Premium x64, I've added a printer that uses an existing driver, and named it 'Canon 2-sided'. After doing so, the Devices and Printers control panel does 'not' show the new printer. This makes it difficult to configure the new printer.
When I attempt to print a page, the printer drop-down menu 'does' show the new printer.
Is there some way to insure that the control panel lists the new printer?
