You can only open the print dialog for the user, and that is as it should be. 您只能为用户打开打印对话框，这应该是应该的。 If you only want to print the text document, there are a couple ways you can trigger the print dialog for it. 如果您只想打印文本文档，可以通过几种方法触发打印对话框。 They require following the Same Origin Policy (your HTML and TXT files need to be in the same domain). 它们需要遵循同源策略 （您的HTML和TXT文件需要位于同一个域中）。
The simplest way is to open a popup window with the text file, and call print on the window handle returned: 最简单的方法是打开一个带有文本文件的弹出窗口，并在窗口句柄上调用print返回：
w = window.open('text.txt');
w.print();
If you want the user to preview the text file, you could use an iframe instead: 如果您希望用户预览文本文件，则可以使用iframe代替：
I recommend keeping JS out of HTML, this is just for example 我建议将JS保留在HTML之外，这只是一个例子
<iframe id="textfile" src="text.txt"></iframe>
<button onclick="print()">Print</button>
<script type="text/javascript">
function print() {
var iframe = document.getElementById('textfile');
iframe.contentWindow.print();
}
</script>

You are correct that window.print() just opens the print dialog for the current web page. 你是正确的window.print()只是打开当前网页的打印对话框。
I would suggest that you write JavaScript code to open a new window, load the text into that window, and then call the print() function on that window. 我建议你编写JavaScript代码来打开一个新窗口，将文本加载到该窗口，然后在该窗口上调用print()函数。

If you just do not want to delete the contents of the page and print some text from a file, you can do so here: 如果您只是不想删除页面内容并从文件中打印一些文本，可以在此处执行以下操作：
<body>
....some tags....
<script type="text/javascript">
// or onclick function
$.load('test.txt', function( printContent ){
history.pushState( printContent, 'Print title', '/print_page' );
document.write( printContent );
if( window.print() ){
document.location = '/back_page/';
// or history.go(-1);
} else {
document.location = '/history/';
}
});
</script>

You can do this by creating a web service. 您可以通过创建Web服务来完成此操作。
