ECONNREFUSED when printing by network

Dieses Issue hat noch niemand übernommen.

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??

Start with the supplied escpos.Network(ip, port) call and the ECONNREFUSED connection to 192.168.1.119:9100. Reproduce the network-printing path and compare it with the working USB path; done means determining whether the failure is in the library or the printer/network endpoint.
