Using multiple LAN thermal printer

[azizie94]

Hi everyone, I already test this package with my LAN thermal printer and everything working fine. The issue is when Im trying to send my data to multiple printer.

I have 2 LAN printer, when I send data to print for both printer:

• 1st printer print fast.
• 2nd printer print quite long but is still print just the timing I think its not normal.

Those anyone here have face this problem ? May I know what is the solution?

Hi there @azizie94 sorry about the long delay on the reply.
Could you post how your setup along with the printer models?
Something like:

EPSON TM-T82 (printer1) <---> web server <---> EPSON TM T-58 (printer2)

And also what is your PHP version and Laravel version when you are testing this package.

Hi @charlieuki,

I have 3 event which is OrderCreated, PrintOrderDetail, PrintDocketDetail.

The flow is, once I create an order I will publish OrderCreated Event.

Once the OrderCreated event published, the PrintOrderDetail and PrintDocketDetail event will run simultaneously.

event PrintOrderDetail - 1st printer
/**
* Handle the event.
*
* @param object $event
* @return void
*/
public function handle(OrderPrinter $event)
{
$setting = Setting::firstWhere('pos_id','POS1');
$branch = Branch::firstWhere('id',1);
$order = $event->order;
$mid = '30001001';
$store_name = 'KIDDYTOPIA';
$store_address = strtoupper('GYRO HOLDING SDN BHD'."\n".$branch->address.' '.$branch->postcode.' '.$branch->city_info->name.' ,'.$branch->state_info->state.'.');
$store_phone = $branch->contact;
$store_email = $branch->email;
$store_website = '';
$tax_percentage = 0;
$transaction_id = $order->code;

    // Init printer
    $printer = new ReceiptPrinter;
    $printer->init(
        'network',
        $setting->order_printer_ip,
    );

    // Set store info
    $printer->setStore($mid, $store_name, $store_address, $store_phone, $store_email, $store_website);

.....

event PrintDocketDetail - 2nd printer
/**
* Handle the event.
*
* @param object $event
* @return void
*/
public function handle(DocketPrinter $event)
{
$setting = Setting::firstWhere('id',1);
$branch = Branch::firstWhere('id',1);
$order = app('product')->session($event->tableId)->getContent();
$table = Table::firstWhere('id',$event->tableId);
$mid = '30001001';
$store_name = 'KIDDYTOPIA';
$store_address = strtoupper($branch->name."\n".$branch->address.' '.$branch->postcode.' '.$branch->city_info->name.' ,'.$branch->state_info->state.'.');
$store_phone = $branch->contact;
$store_email = $branch->email;
$store_website = '';
$tax_percentage = 0;

    // Init printer
    $printer = new ReceiptPrinter;
    $printer->init(
        'network',
        $setting->order_printer_ip,
    );

    // Set store info
    $printer->setStore($mid, $store_name, $store_address, $store_phone, $store_email, $store_website);

....

So when OrderCreated event publish, the PrintOrderDetail and PrintDocketDetail listen successfully but the 1st printer will print the result fast, the 2nd printer take 15-30 second to print.

I am using Laravel 9 and php 8.
