Comment 57 for bug 1032456

Thanks, the behavior is like with many other Canon printers and I have added an appropriate exception rule to the CUPS USB backend in Quntal. I t is not decided yet whether we issue another Precise SRU with all collected new exception rules. For the time being stay with

lpadmin -p <printer> -o usb-unidir-default=true

You only need to do the setting once, it survives reboots.
