使用 Javascript 打印 ZPL 标签

Question

我正在使用此示例来打印标签： https://www.neodynamic.com/articles/How-to-print-raw-Zebra-ZPL-commands-from-Javascript/ 一切正常，除了如果我想每次点击打印超过 1 个标签，它会允许我这样做，例如，如果我使用 for 或 while 循环打印，但每次 for 都会在说打印的警报上移动现在每次都出现这是最后一部分在我的代码中的样子 n = 0;

while (n < 2) {
          n ++;

        var cmds =  "^XA";

        cmds += "^FO480,21^ARN,1,90^FD/^FS";  
        cmds += "^FO62,36^AUN,90,100^FDEL ZAPATON^FS";
        cmds += "^FO0,135^ARN,60,14^FDDama 4^FS";
        cmds += "^FO0,200^ARN,60,40^FD^FS";
        cmds += "^BY2,2,100";
        cmds += "^FO10,270^BC^FDE0430601926027^FS";
        cmds += "^FO410,273^AUN,100,75^FD0.50^FS";
        cmds += "^FO50,20^GB530,120,6,B,0"

        cmds += "^XZ";
        cpj.printerCommands = cmds;


        //Enviar impresion a Zebraimpresora
        cpj.sendToClient()

如果您想打印多份，只需将其加倍即可。

var zplStr =
`^XA
^FO480,21^ARN,1,90^FD/^FS
^FO62,36^AUN,90,100^FDEL ZAPATON^FS
^FO0,135^ARN,60,14^FDDama 4^FS
^FO0,200^ARN,60,40^FD^FS
^BY2,2,100
^FO10,270^BC^FDE0430601926027^FS
^FO410,273^AUN,100,75^FD0.50^FS
^FO50,20^GB530,120,6,B,0
^XZ`;

const numOfCopies = 2;
var cmds = new Array(numOfCopies).fill(zplStr).join("\n");
console.log(cmds)
