Printing in a Java applet

I am trying to write a Java applet that can print. It is easy enough to disable print security in Microsoft Internet Explorer. However, I cannot seem to find a way to do this in Netscape Navigator 4.04. Can anyone help me with this problem?

In order to be able to print from an applet, it has to be signed. Here is some doc. about the security model used in Java 1.1:

http://www.javasoft.com/products/jdk/1.2/docs/guide/security/spec/security-spec.doc1.html#18314

Here is a page at the Netscape site intended for Java developers who are writing applets or libraries that need access to local system resources:

http://developer.netscape.com:80/docs/manuals/signedobj/capabilities/index.html

That's for the theory. The following page explains you  how to sign with an example:

http://java.sun.com/security/usingJavakey.html

If you want some sample code for printing from an applet, you can read at the end of this page:

The discussion should also interest you. Be sure to have full JDK 1.1 support before beginning:

when using jdk 1.02 simply generate a html file and open this in a new browser window, then u can print from the browser....( u can also print directly from jdk 1.02 , but then u need to know which system u r using (e.g sending a dos string to print a file) but u will have many problöems with the layout etc.
using jdk 1.1, u can use the print functionality.

Thank you for help. Unfortunately, I did not phrase the question correctly. We are currently implementing the applet in Java 1.1 because of its print capability. We need to use Java 1.1 because our applet must be cross-platform capable. Plus it is a graphics applet, so we have to print graphics rather than text. The applet renders a vector graphics file in real-time. We would appreciate any help you can provide. We have also increased the points on this question, since it seems harder than we first thought.

That's what we were afraid of. Signed certificate must be obtained from a third party. And for our project, we need to generate it ourself. We were hoping there is an easy way of turning off the security feature in Netscape Navigator like in Internet Explorer. I guess now the question is how do we sign our own certificates? I'll ask that in another thread.
