Seen this before with 5550 and 5610 models. If you uninstall both printers with this printer disconnected from the computer, and then install the printer again following the installation procedures in which the software is installed first and then you attach the USB printer when it tells you to, then you will only have 1 printer shown vs a copy of the other. This can happen if you have this printer plugged into a different USB port etc after a move of computer hardware etc. The last time I saw this it was when moving a users setup from one office to another and they had the printer and a bunch of other stuff plugged into a USB HUB, and when I plugged the printer in directly the (copy) was introduced. Following the process above fixed this.
