我可以轻松打印单个 PDF 文件，但是当有更多文件时我不知道如何打印。

You can call print()multiple times in your code, resulting in the files being printed one after the other:
您可以print()在代码中多次调用，导致文件一个接一个打印：
function PrintAll() {
var pages = ["page1.pdf", "page2.pdf", "page3.pdf"];
for (var i = 0; i < pages.length; i++) {
var oWindow = window.open(pages[i], "print");
oWindow.print();
oWindow.close();
}
}

Either do as Shodow Wizard suggests and print out the files sequentially or concatenate the files server-side.
按照 Shodow 向导的建议进行操作并按顺序打印文件或在服务器端连接文件。
You could make an ajax request with the fine names that the user wants to print, concatenate them server side, return the concatenated pdf and then print that out. The concatenation implementation would depend on what server-side language you are using.
您可以使用用户想要打印的精细名称发出 ajax 请求，将它们连接到服务器端，返回连接后的 pdf，然后将其打印出来。连接实现将取决于您使用的服务器端语言。
