Guide on creating a Java Applet , Printing without prompt

Question

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

1. Shows the HTML page & a Print button
2. Print Order

Answer 1

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