On recent versions of Firefox (since 19), you have to disable the bugged and native PDF viewer (pdf.js) in about:config. Set the pdfjs.disabledproperty to trueand you will see the print window appearing using your script.
在最新版本的 Firefox 上（自 19 起），您必须在about:config. 将该pdfjs.disabled属性设置为true，您将看到使用您的脚本出现的打印窗口。
If there's a download starting, set the plugin.disable_full_page_plugin_for_typesproperty to application/pdf.
如果开始下载，请将plugin.disable_full_page_plugin_for_types属性设置为application/pdf。

This is error of Src in iframe with full url src="domain.com/file.pdf"
这是 iframe 中 Src 的错误，带有完整的 url src="domain.com/file.pdf"
you can try
你可以试试
$('.print').click(function () {
var domain = location.protocol + "//" + location.host;
var iframe = '<iframe src="'+domain+'/test.pdf" id="print-iframe" name="print-iframe"></iframe>';
$('body').append(iframe);
window.frames["print-iframe"].focus();
window.frames["print-iframe"].print();
});
