RS-232/C Serial Data Interface

Specifications	2400 to 115000 baud parity, bits/character 7 or 8 data bit XON-XOFF, RTS/CTS, or DTR/DSR handshake protocol required 750mA at 5 V from pins 1 and 9
Limitations and requirements	You must use a null-modem cable to connect to the printer or a null-modem adapter if using a standard modem cable. Maximum cable length of 15.24 m (50 ft). You may need to change printer parameters to match the host computer.
Connections and configuration	The baud rate, number of data and stop bits, the parity, and the XON/XOFF or DTR control must match those of the host computer.
