Rongda 76mm Receipt Printer Interface Introduction

one,76mm Receipt Printerserial interface

The serial interface of the 76mm series receipt printer adopts the RS-232 standard, with a communication baud rate of 4800bps, 9600bps, 19200bps or 38400bps selectable (adjustable via DIP switch), 8 data bits, no parity, 1 stop bit, and supports RTS/CTS and XON/XOFF handshake protocols.

The pin functions of the printer serial interface are defined as follows:

II. Parallel Interface of the Printer

The 76mm series printers feature a 25-pin Parallel connector for 8-bit parallel transmission and support the BUSY/nAck handshake protocol.

The pin functions of the printer parallel interface socket are defined as follows:

III. Printer's Ethernet Interface

The 76mm series printers feature a standard RJ45-8P Ethernet interface socket that supports 10M/100M networks and offers adaptive transmission speed.

IV. Cash drawer interface of the printer

The printer's cash drawer uses the RJ-11 standard, a 6-pin connector, and outputs a DC 24V/1A power signal to drive the cash drawer. Simply insert the RJ-11 connector into the cash drawer interface to open the cash drawer via the printer.

The pin functions of the printer's cash drawer interface are defined as follows:
