javascript - 是否可以通过浏览器打印 JavaScript 代码将卡片打印到 ZEBRA ZXP 系列 3 打印机？

Question

我正在使用 Zebra 技术提供的 JavaScript 代码，但我不断收到“发生错误”消息。是否只能通过浏览器打印打印标签，而不是卡片？我正在使用 Zebra ZXP Series 3 证卡打印机

进行打印

我已附上他们提供的我正在使用的代码。

下面是他们提供的示例代码。它的名字叫Browser Print

DevDemo.js 和 Index.html

var available_printers = null;
var selected_category = null;
var default_printer = null;
var selected_printer = null;
var format_start = "^XA^LL200^FO80,50^A0N36,36^FD";
var format_end = "^FS^XZ";
var default_mode = true;

function setup_web_print()
{
	$('#printer_select').on('change', onPrinterSelected);
	showLoading("Loading Printer Information...");
	default_mode = true;
	selected_printer = null;
	available_printers = null;
	selected_category = null;
	default_printer = null;
	
	BrowserPrint.getDefaultDevice('printer', function(printer)
	{
		default_printer = printer
		if((printer != null) && (printer.connection != undefined))
		{
			selected_printer = printer;
			var printer_details = $('#printer_details');
			var selected_printer_div = $('#selected_printer');
			
			selected_printer_div.text("Using Default Printer: " + printer.name);
			hideLoading();
			printer_details.show();
			$('#print_form').show();

		}
		BrowserPrint.getLocalDevices(function(printers)
			{
				available_printers = printers;
				var sel = document.getElementById("printers");
				var printers_available = false;
				sel.innerHTML = "";

					}
				}
				
				if(!printers_available)
				{
					showErrorMessage("No Zebra Printers could be found!");
					hideLoading();

我已联系他们的技术支持，但没有结果。有任何想法吗？我认为发生的情况是 is_error 从未被设置为 '0'

Answer 1

Browser Print仅适用于 Zebra 标签和收据打印机。目前不支持证卡打印机。
目前可以通过 3 种方法打印卡片。 Drivers , .NET 应用程序使用 the SDK ，或使用 Link-OS SDK 的 Java 应用程序.
