The interface Introduction of 76mm thermal receipt printer

I. Printer Serial Port

76 printer's serial port is RS-232 standard, and communication baud  rate can be 4800bps, 9600bps, 19200bps or 38400bps optional (can  be adjusted via DIP switches). It is 8 bits of data, no parity, 1 stop  bit, support RTS / CTS and XON / XOFF handshake protocol.

The printer serial port pin functions are defined as follows:

II. Printer Parallel Port

76 printer’s parallel interface is for 25PIN socket. 8-bit parallel transfer and supports the BUSY / nAck handshake protocol.

Printer parallel interface socket pin function is defined as follows:

III. Printer Ethernet Port

The Ethernet interface socket of 76 is RJ45-8P, support10M/100M network, and the transmission speed is adaptive.

IV. Printer Cash Drawer Port

The printer cash drawer port is with standard RJ-11, 6-wires socket, output DC 24V/1A and work by power signal. Plug the RJ-11 crystal plug into cash drawer port and then you can open the cash drawer via printer.

Printer cash drawer interface pin functions are defined as follows:
