Java print service and Applets (IE)

[lipkerson]

Hi

I got a strange problem. I use Java print service to send to printer data that are in byte array.The application is applet-it is not signed so JVM asks every time if I really want to send data to printer.It is ok to me- It's all working fine and the printing methods are excellent.
There were excellent until i discovered that they perfectly working on windows that is in "administrator mode".
If the user is common and I use Internet explorer the applet doesn't print at all.
It's strange becouse in Firefox it's always working fine.

I thought that it is a java.policy problem so I added

grant {
// Permission to print without confirmation questions:
permission java.lang.RuntimePermission "queuePrintJob";
};

but it is a way to avoid problem with asking by JVM if the applet is trustworthy and it's not solving my problem at all.

the applet doesn't print at al

Do you get any error messages in the browser's Java Console?

What versions of the browsers and the jre are you using?

Hi

There is no errors in web browser's console. I use windows 7 with IE 8.

No ideas about Win7.
What version of the jre?

I'm interested because I've had a problem with permission differences between different browsers for years. Mine problem is an applet trying to read files on my disks. It works in older browsers like Mozilla and Netscape but not current ones like FF, IE8 or Chrome.
I've asked the question on Sun's site and on the JavaRanch site. No luck getting the answer yet.

I use JRE6U20.

And for the reading files from disk: i use standart reading methods in signed applet and it works ok. The bytes from file are read correctly and with no exceptions in any browsrer (maybe except Chrom but my problem is maybe in the way writing some stuff in user temp dir).

What kind of methods do You use to read bytes in files?
Have You tried to lunch applets from applet viewer i.e. in netbeans the defoult way to see the applet is by lunching it in applet viewer? I write this becouse the problem might be much more trivial then issues with permissions etc.
