This is the first time of our working with POS printer, So we are totally lost. Can anyone help up with this? Thanks in advance. Detail :

    *
    * Use a WindowsPrintConnector with the share name to print.
    *
    * Troubleshooting: Fire up a command prompt, and ensure that (if your printer is shared as

    *
    *  echo "Hello World" > testfile
    *  copy testfile "\\%COMPUTERNAME%\Receipt Printer"

You supply null to your Printer.

$connector = null;
$printer = new Printer($connector);

Instead, you should try this:

$printername="EPSON_LX_310";        
$connector = new WindowsPrintConnector($printername);
$printer = new Printer($connector);

Hope this will help someone else. You need to first install drivers. Then write your code as below. The WindowsPrintConnector is the one used to create the connector object. This works for me with Laravel.

use Mike42\Escpos\PrintConnectors\FilePrintConnector;
use Mike42\Escpos\PrintConnectors\WindowsPrintConnector;
use Mike42\Escpos\Printer;
require 'C:\wamp64\www\myappname\vendor\autoload.php';
try {
    // Enter the share name for your USB printer here


    $connector = null;
        $connector = new WindowsPrintConnector("E-PoS 80mm Thermal Printer");
        /* Print a "Hello world" receipt" */
        $printer = new Printer($connector);
        $printer -> text("Hello World\n");
        $printer -> cut();

        /* Close printer */
        $printer -> close();
    } catch (Exception $e) {
        echo "Couldn't print to this printer: " . $e -> getMessage() . "\n";
    }
