General Electric TermiNet 340 printer doc?

[Henk Gooijen]

I picked up a really heavy line printer last week.
It is a General Electric TermiNet 340. My searches for doc
were not very successful. It seems to be a line printer
that prints 340 lines of 132 characters per minute!

At the rear side near to the floor is a large rectangular
connector. Lucky me, the previous owner had a connection
cable. It is a ribbon cable. At one side is the mating
rectangular plug, at the other side is an IDC header.

Is it possible that this printer is also sold by others using
a different name?  So far I have not been able to find any
documentation.  I'd love to get this beast operational!

Thanks for pointers,
- Henk
