As Rob said, they are interdependent. Photoshop has to convert the 16bit aRGB image data to the scanner/paper profile (via the appropriate rendering intent, etc) I've selected and then to 8bit to drive the scanner. The possibility of a lot of round off error is minimized by using 16bit files.
The print driver isn't quite as sophisticated about the conversions, and you can see the difference.
