Re: Printing in Java

I'm not sure if you've figured this thing out yet so I'll try a quick
answer.

How about the browser sandbox security?  Is it turned off?  Typically
printing is a secured resource just like disk access.
It has been a really long time since I tried applets but I remember that you
need a "signed" applet jar or to simply change the browser settings to allow
applets access to the browser/desktop's resources.
