指导没有提示创建一个Java小程序，打印 [英] Guide on creating a Java Applet , Printing without prompt

问题描述

好吧，我创建了一个基于网络的POS采取订单。我的问题是如何创建一个Java小程序;

Well I have created a web-based POS to take order. My question is how do I create a Java-Applet;

1. 显示HTML页面和放大器;打印按钮


2. 而不提示打印命令（无对话框）

附加信息：它的工作原理是这样的。服务员会从电脑（POS）键的命令，当他们击中打印，它将检测在厨房打印机的腹膜内地址，然后立即打印出订单，而不提示。我其实在寻找参考/指南，可以帮助我开始。任何意见将是有帮助。谢谢

Additional Information : It works like this. The waiter will key the orders from the computer(POS) , when they hit print, it will detect the I.P address of the printer in the kitchen,then print out the orders immediately without prompt. I am actually looking for reference/guide which can help me start on. Any Advise will be helpful as well. Thank you

推荐答案

您不能这样做，出于安全考虑。如果你能，小程序就已经成为臭名昭著的打印10+网页，当您访问不法网站特别优惠。

You cannot do that for security reasons. If you could, applets would already have become notorious for printing 10+ pages of 'special offers' when you visit unscrupulous web sites.

OTOH，如果客户愿意接受一个提示小程序在启动时，可以进行数字签名code。

OTOH, if the client is willing to accept one prompt at applet start-up, you could digitally sign the code.
