The LabelManager PC is a label printer, made by Dymo. It has a usb port (usb 1.1), and a separate power supply (external brick, 9V DC, 1.3 A). On the front of the printer is a status light (LED?) that is red when the printer is turned on but not ready (not connected for example) and turns green when the printer is ready. The printer requires Windows (98, 2000, Me or XP) according to Dymo.
The status light colors have these meanings (from the manual):
green                                      - normal
solid red                                 - no usb connection
flashing red                           - motor is jammed
alternating red and green   - communications error
no light                                    - no power

Labels: the printer uses Dymo D1 tapes.
