Adding Canon iRC 3170i to CUPS??

[CH Choo]

Hi,
I have this multifunction printer that I want to add to the Linux print server.  Cups is asking information like Device and Device URI when I try to add printer.

Does anyone know what should I entered for this two fields or where can I get this information?  What about installing printer driver, should I install the driver somewhere first?

Thanks for your help in advance.
