Nur mal so ins Blaue. Schau mal diesen Link an: http://www.henningweiler.de/?p=70 Dort wird auf eine File-URI geschrieben die udev in /dev/usb anlegt. Evt. kann man sich auch eine udev-Rule basteln die bessere Devicenamen vergibt. Zudem habe ich noch Folgendes gefunden: "Make sure that your printer is uniquely identified by its device URI: For network printers with standard CUPS backends there is no problem, as they have unique IP addresses. For USB printers with the standard CUPS USB backend you are on the safe side as long as you do not connect two printers of the same model to one computer, as CUPS makes URIs from the manufacturer and model name. For two printers of the same model CUPS distinguishes by the serial number in the IEEE-1284 device ID. So talk with the hardware engineers that they expose the serial number in the device ID (HP does it for example). If you cannot use standard CUPS backends and write your own backend, make sure to never let it address printers by /dev/usb/lp0 or similar device files. If you have two or more printers and reboot, they can get assigned to the printers in different order. Also be very careful with the USB vendor and product IDs. There exist completely different printers with the same vendor and product IDs, like most Epsons. The best for identification of locally connected printers is always the device ID, and the serial number for printers of the same model." aus http://www.linuxfoundation.org/collaborate/workgroups/openprinting/writingan...
