Serial interface
RS232C/V.24
Your printer’s serial interface supports the RS232C specification. The
signals are received and transmitted by a 25 pin connector.
Basically 3 lines are already enough for exchanging information between
computer and printer (one receive line, one send line, one line for common
grounding).
