Disabling java applet warning for printing

Avg Bid (USD)
Project Budget (USD)
$30 - $250

Project Description:
I have a little java applet on my webpage that prints ticket and invoice to the DotMatrix printer. (This is my printer: http://is.gd/WBLs6i )

I want to prevent "Java Applet Warning" when I try to print something.

I'm looking for a solution for this.

This is NOT public application. I'm using this java applet with 20-30 client. My clients uses windows XP, windows 7 and Firefox.

Since now, I used it with manualy edit java policy file:

permission java.lang.RuntimePermission "queuePrintJob"; (in java.policy file)

But, it's problem on java upgrade. Because, I need to edit policy file manualy on every client when java is updated :(

Note: I'll share my applet source code after selecting the winner.

Skills required:
Java, Print
