58mm Thermal Receipt Printer Interface Introduction and Explanation

one,58mm thermal receipt printerserial interface

The serial interface of the 58mm series printer adopts the RS-232 standard, with a communication baud rate of 9600bps, 8 data bits, no parity check, 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 58mm Thermal Receipt Printer

The 58mm series printers use a 25-pin parallel interface socket, supporting 8-bit parallel transmission and the BUSY/nAck handshake protocol. The pin functions of the printer's parallel interface socket are defined as follows:

III. Ethernet Interface of 58mm Thermal Receipt Printer

The Ethernet interface socket of the 58mm series printers is a standard RJ45-8P, which supports 10M/100M networks and has adaptive transmission speed.

IV. Cash drawer interface for 58mm thermal receipt printer

The printer's cash drawer uses the RJ-11 standard, a 6-pin connector, and outputs a DC 12V/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:
