date_default_timezone_set("Asia/Karachi");
/* Change to the correct path if you copy this example! */
require __DIR__ . '/../../autoload.php';
use Mike42\Escpos\Printer;
use Mike42\Escpos\EscposImage;
use Mike42\Escpos\PrintConnectors\NetworkPrintConnector;

/* Most printers are open on port 9100, so you just need to know the IP 
 * address of your receipt printer, and then fsockopen() it on that port.
 */
try {
    $connector = new NetworkPrintConnector("10.10.10.6", 9100);

    /* Print receipt" */
    $printer = new Printer($connector);


/* Start the printer */
$logo = EscposImage::load("resources/cafechox.png", false);
$printer = new Printer($connector);

/* Print top logo */
$printer -> setJustification(Printer::JUSTIFY_CENTER);
$printer -> graphics($logo);



    $printer -> cut();

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