I think you are getting confused with the CUPS code that generates the device *URI*, which does replace some vendor strings and remove the manufacturer prefix from the model name if present. But the device-id attribute is what the device gave us, unaltered. > We must be prepared for broken backends, and this fixes easily many > broken ones. I don't accept this. When there are broken backends they ought to be fixed. This is especially true of HPLIP which is supposed to be free software after all. Tim. */
