This should not be a Django matter. 这不应该是Django的事情。 It doesn't matter if the web app is on your local machine, a web app is a web app. Web应用程序是否在您的本地计算机上都无所谓，Web应用程序就是Web应用程序。 You have to make clear in your design if you wish to use a printer as a server or as a client. 如果要使用打印机作为服务器或客户端，则必须在设计中明确说明。

Since I assume that it is more reasonable to print as the end user, you can simply use a bit of javascript calling window.print() on click. 由于我认为以最终用户身份进行打印更为合理，因此您可以在单击时简单地使用一些JavaScript调用window.print() 。
