Getting the browser output into java app.

[Salamina Daniel]

I'd like to launch a java apllication from the browser (I need to print to a dot print matrix and use the print port directly), and it seems that I could use Java Web Start to do that.
Is there any way to import the browser output into the java application (so at the moment that I launch the app. I could print the browser output directly to the printer as ASCII text)?
Best regards
