Re: One question about usb backend of Mac OS X

Pangpang,

Panther handles multiple printers of the same model on the usb bus.
The device uri contains the printer's s/n, and if the s/n is missing we
synthesize one from the location id. If you find any problems, please
report a Radar bug.

Thanks.

-Paul
