Can Browser Print Applet's Output?

I have written an applet that creates a graph from the results of a query of our Oracle database. The graph looks good in the browser (Netscape 3.0), but if I go to print the broswer page, nothing in my applet shows up. Text and graphics above and below the applet will print fine, but there will just be a big blank spot where the graph should be.

That is normal. Unfortunately, Netscape makes no effort to find out what the Java program draws onto the screen. (It could, in theory, try to have that subwindow redraw itself and capture the output, then scale the screen pixels to the printer. But it doesn't.) And, there is no Java API for printing.

There will, at some point in the future, be Java support for printing. Sun and Adobe are jointly working on an improved graphics model and printing support. When that happy moment comes, your Java applications will be able to print. Whether or not that capability will extend to applets is anyone's guess for now.
