Serial interface
V.24/RS232C
Your printer’s serial interface supports the RS232C specification. The
signals are received and transmitted by a 9 pin connector.
Basically 3 lines are already enough for exchanging information between
computer and printer (one receive line, one send line, one line for com-
mon grounding).
