PHP - 打印RAW未打印（热敏打印机）

Question

I already create PHP function using ext printer.dll and its work when print TEXT only.

This my PHP function

$handle = printer_open('Printer Name'); 
        printer_start_doc($handle, 'My Document200');
        printer_start_page($handle);
        $ret = printer_write($handle,'Hello');
        printer_end_page($handle);
        printer_end_doc($handle);
        printer_close($handle);

it works .

But when iam print RAW script it returned blank (but printer is running) This is my PHP function for RAW (using ZPL command)

            $handle = printer_open('Printer Name'); //or it could be \\pcname\printername
        printer_start_doc($handle, 'My Document200');
        printer_start_page($handle);
        printer_set_option($handle, PRINTER_MODE, 'RAW');

        $esc = chr(94);
        $data = ' ';
        $data .= $esc . 'XA';
        $data .= $esc . 'FX  Third section with barcod' ;
        $data .= $esc . 'BY1,5,30' ;
        $data .= $esc . 'FO600,130' . $esc . 'BC' . $esc . 'FD1234' . $esc . 'FS';
        $data .= $esc . 'XZ';

        $ret = printer_write($handle,$data);
        //close the printer handle
        printer_end_page($handle);
        printer_end_doc($handle);
        printer_close($handle);

I am using Wincode C342 Printer which is support ZPL command. What is wrong? is it because driver?
