使用PHP打印到热敏收据打印机使用PHP

Question

我有以下代码可以使其能够将某些内容打印到热敏收据打印机。

if ($_GET['action'] == 'print') 
{ 
    $printer = "\\\\localhost\\zebra"; 

    // Open connection to the thermal printer 
    $fp = fopen($printer, "w"); 
    if (!$fp){ 
     die('no connection'); 
    } 

    $data = " PRINT THIS "; 

    // Cut Paper 
    $data .= "\x00\x1Bi\x00"; 

    if (!fwrite($fp,$data)){ 
     die('writing failed'); 
    } 

} 

虽然，当我运行它时，没有任何事情发生，没有错误。如何从PHP打印？

试试这个...

<?php 
if ($_GET['action'] == 'print') 
{ 
$printer = "\\\\localhost\\zebra"; 
if($ph = printer_open($printer)) 
{ 
    $data = " PRINT THIS "; 
    // Cut Paper 
    $data .= "\x00\x1Bi\x00"; 
    printer_write($ph, $data); 
    printer_close($ph); 
} 
else die('writing failed'); 
} 
?>
