In addition to what Remy mentioned.
Stops bits have almost always been 1 for about 25 years now.

Did you check the dip-switch settings on the printer?
Section 12.3.1 of that manual says:
The baud rate may be 4800, 9600 or 19,200.
The parity may be even or odd or none
The stop bit is 1 (fixed)
The handshaking can be just about anything.
Double check your DIP Switch settings.

Put a  break-out-box in the line, and check for proper DTS/DSR/RTS/CTS
functioning.  I have yet to find a printer that handles those in the
manner that Microsoft dictates. (That is to say, the printers handle
them properly, but MS doesn't) I always have to cross signals, and
short some to get a printer working serially with hardware
handshaking.
