[Coco] CNR Engineering SP-3 (serial to parallel interface) - Manual?

[Arthur Flexser]

Generally, these interfaces required little in the way of documentation.
You basically just plug one end into the CoCo's serial port and the other
end to the (old style, dumb) printer.  There should also be something for
setting the baud rate.  That's about it.
