    public function test_print(){
        $printer_ip = env('PRINTER_IP');
        $label_width = env('LABEL_WIDTH');
        $label_height = env('LABEL_HEIGHT');
        $text_x_axis = env('TEXT_X_AXIS');
        $text_y_axis = env('TEXT_Y_AXIS');
        $text = env('TEXT');
        $text_font = env('FONT_TEXT');
        $text_size = env('TEXT_SIZE');

        $text_box_width = env('TEXT_BOX_WIDTH');
        $text_box_height = env('TEXT_BOX_HEIGHT');
        $text_box_border = env('TEXT_BOX_BORDER');


        $barcode_x_axis = env('BARCODE_X_AXIS');
        $barcode_y_axis = env('BARCODE_Y_AXIS');
        $barcode_data = env('BARCODE_DATA');
        $barcode_type = env('BARCODE_TYPE');
        $barcode_height = env('BARCODE_HEIGHT');
        

        $label = Label::create(Unit::MM(), $label_width, $label_height)
            ->charset(Charset::UTF8())
            ->add(Element::textBlock($text_x_axis, $text_y_axis, $text, $text_font, $text_size)->box($text_box_width, $text_box_height, $text_box_border)->anchor(Anchor::CENTER()))
            ->add(Element::barcode($barcode_x_axis, $barcode_y_axis, $barcode_data, $barcode_type)->height($barcode_height));

        (new Printer(new NetworkConnector($printer_ip)))->print($label);

        return redirect()->back()->with('execute','Test print function executed');
    }

this is the code, all code same as in readme but i change it to variable.

Use this

(new Printer(new NetworkConnector($printer_ip), Compiler::create(new Fingerprint())))->print($label);

[warfee]

alright..i will try this one

[warfee]

There are some few error appear after use code (new Printer(new NetworkConnector($printer_ip), Compiler::create(new Fingerprint())))->print($label); but i try to solve the error by include library path use PhpAidc\LabelPrinter\Compiler; use PhpAidc\LabelPrinter\Language\Fingerprint; use PhpAidc\LabelPrinter\Language\Fingerprint as Handlers; and amend the code to (new Printer(new NetworkConnector($printer_ip), Compiler::create(new Fingerprint(2))))->print($label);. Other new error comes out PhpAidc\LabelPrinter\Exception\CouldNotConnectToPrinter stream_socket_client(): unable to connect to tcp://192.168.1.254:9100 (Connection timed out)

*new Fingerprint(2) for this one i just put the value for dummy and i don't know what value use for.Please correct me if there is a mistake.

Check your printer configuration (network settings) and so on. This is an network issue.

Hi, thanks alot for your response..i able to print the printer lable..project file that run locally and connect to printer..i want to ask, its that possible to command from server(if i host it to cloud) to specific printer?

[jhaoda]

You can share the printer port to the internet (very bad idea) or create VPN tunnel from cloud server to local network.

alright..noted! thanks alot

One more, got issue text or barcode not printed on the label..it that configuration label format(width n etc) or related to the computer..?
