Ah... It probably is a Centroics 703. Is it the right
colour ir is it
'battleship grey' like the computer? IIRC the rist Radio Shack 'Line
Printer' (which was not a ture line pritner, of course) was actually a
Centroics 703 with grey case mouldigns. No internal changes at all.
Instead of me trying to describe it, how about I provide some color photos? :-)

If this is the printer I am thinking of (and from your
description of the
ribbon I think it is), the carriage motor is an AC shaded pole thign that
runs all the time. It drives a belt acorss the printer. Solenoids in the
carriage grab the top or bottom run fo the belt to move the carriage. Odd..
No it uses a normal belt system that isn't running all the time and is firmly
connected to the print head. The only thing that runs all the time is the large fan in it.
It's not a Radio Shack model, it has lots of buttons on the front. It does look very
similar though.
Were you not supposed to ever replace the belt, just re-ink it in place? What about when
the pinch rollers for the ribbon wear out?
