ECONNREFUSED when printing by network

Open gzimbron opened this issue 1 year ago • 0 comments

USB interface tested and worked.

But I'm getting this error while trying to print by Network interface:

Error: connect ECONNREFUSED 192.168.1.119:9100
    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1487:16) {
  errno: -61,
  code: 'ECONNREFUSED',
  syscall: 'connect',
  address: '192.168.1.119',
  port: 9100
}

Ping to printer:

Code:

const escpos = require('escpos');
escpos.Network = require('escpos-network');

const netPrint = (ip: string, text: string, encode: string, fontSize: number, port: number) => {
	const device = new escpos.Network(ip, port);

	const options = { encoding: 'GB18030' };
	const printer = new escpos.Printer(device, options);

	device.open(function (err: unknown) {
		if (err) {
			console.log(err);
			return;
		}

		printer
			.font('B')
			.align('LT')
			.style('NORMAL')
			.size(fontSize, fontSize)
			.marginBottom(1)
			.encode(encode)
			.text(text + '\n\n')
			.cut()
			.close();
	});
};

export default netPrint;

Anyone had this problem??
