use centos7 with kde. and in cups (localhost:631) there is no usb to select.
its an lexmark Ms510dn per usb cable connected to my box.
surely the printer is attached to usb and is in operation.
this is the dialogue in cups...no usb
meanwhile i cant find a printericon in my settings...? hmm.Local Printers: Serial Port #1
