George, can you do sudo usb_printerid /dev/usb/lp0
and post the output here? Please note also that your problem is not the problem originally reported here. Your problem is that CUJPS cannot cope with a USB printer which does not supply its device ID. Every native USB printer supplies its ID< but your adapter cable is a bad implementation, it does not pass on the device ID which the printer supplies to its parallel port. Please report a separate bug on this, perhaps even better directly upstream at http://www.cups.org/ (problem will occur the same way if you are using another Linux distribution than Ubuntu or Mac OS X). -- Printer is not detected properly over USB https://bugs.launchpad.net/bugs/35638 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
