PHP escpos Printing

Question

有人能帮忙吗?

你好,我用"EPSON TM-T82II收据"打印账单。我使用php代码

 <?php
   require_once(dirname(__FILE__) . "/Escpos.php");
 try {
 $connector = null;
  $connector = new WindowsPrintConnector("EPSON TM-T82II Receipt");
  /* Print a "Hello world" receipt" */
$printer = new Escpos($connector);
$printer -> text("Hello World!n");
$printer -> cut();
/* Close printer */
$printer -> close();  
} catch(Exception $e) {  
echo "Couldn't print to this printer: " . $e -> getMessage() . "n";
}   
Iam getting this error "Couldn't print to this printer: Printer

"EPSON TM-T82II收据"无效。使用本地端口(LPT1, COM1等)或者smb://计算机/打印机符号。"

您应该完全按照错误提示进行操作-您需要使用WindowsPrintConnector("LPT1")或WindowsPrintConnector("smb://XXX")而不是WindowsPrintConnector("EPSON TM-T82II Receipt")，其中XXX是您的打印机的网络路径
