Example that is printing? about receiptline HOT 6 CLOSED

Thank you for using receiptline.

You can print with TM-T88V.
In order to print with the designer, please edit printer.json.
Then, type tm_series1 in the text box and send.

"tm_series1": {
    "host": "x.x.x.x",
    "port": 9100,
    ...
},

The following code is an example of printing.

const net = require('net');
const receiptline = require('receiptline');

const data= 'hello, world!';

const printer = {
    host: 'x.x.x.x',
    port: 9100,
    cpl: 42,
    encoding: 'cp437',
    upsideDown: false,
    gamma: 1.8,
    command: 'escpos'
};

const socket = net.connect(printer.port, printer.host, () => {
    socket.end(receiptline.transform(data, printer), 'binary');
});
socket.on('error', err => {
    console.log(err.message);
});

Thanks.
I can work with this.
What is the best way of using the printers.json file in the distribution?
Is this a list of example printers that can be supported with their settings?

from receiptline.

Instructions for printer.json can be found in "ReceiptLine Designer" in README.md.

Most of the items are the same as the printer parameter of the receiptline.transform() method.

Thanks!

@receiptline thank you for clarifying.
I am trying to translate this for browser and also have looked into the example en.html file in this package.
I can render the receipt in browser but do not see a way to send to printer from browser.
The net module is not available in browser only in nodejs. Is there an alternate way to send it to printer via IP?
Is there a complete browser print example I have overlooked in the package?

// receiptline
const command = receiptline.transform(text, printer);
// navigator.serial
const port = await navigator.serial.requestPort();
// open the port
await port.open(options);
// get the writer
const writer = port.writable.getWriter();
// convert command string to Uint8Array
const binary = ...
// write Uint8Array
await writer.write(binary);
// close the writer
await writer.close();
// close the port
await port.close();

Thanks.
