我需要打印一个DataMatrix与载体返回和换行。我的打印机是一个斑马GK 420 t。我在斑马设计师的标签，当标签打印从斑马设计师的CR和LF工作，但当我导出标签到PRN文件，打印与PHP，CR和LF不工作。
PHP代码

<?php

    var $host = "";
    var $port = "";
    var $error = "";
    var $prn = "";

    function __construct($host,$port) {
        $this->host = $host;
        $this->port = $port;

        $this->prn = "CT~~CD,~CC^~CT~
